  1. OK. You or someone you care about has been diagnosed with COPD. Chronic obstructive pulmonary disease is an affliction that covers a multitude of sins, insofar as it covers a spectrum of lung conditions, including emphysema and chronic bronchitis. Like the other C word, the prognosis is not good, although it is not an immediate death sentence unlike some particularly aggressive cancers. In reality, a diagnosis of COPD shaves a substantial portion from your life expectancy, as traditional medicine considers it “incurable”. Traditional medical wisdom then switches to the next immediate solution, which is quality of life. I will not argue with this point, however I will dispute the argument that smoking is the only contributor to such a debilitating illness. Being a seriously premature baby, and spending my early adult life inhaling toxic fumes from soldering, I would estimate these factors contributed significantly to my current condition. Most importantly though, being an engineer and someone who is focussed on rationality, logic and objectivity, I want to approach the whole subject holistically. After all, it was cigarettes that got me into this mess, and that question would be, why, on God’s green earth, would someone with a history of poor lung capacity, take up the wicked weed at 17?

    If we are ever going to deal with the horrors of tobacco, we need to dig a bit deeper into the soil of society. For me, the attraction was social acceptance, a sharing of communal values that is so critical as a teenager. What that “acceptance” offered was simple. A temporary lid on all the abuse I suffered as a child, emotionally, mentally and physically. Personally, I don’t think I did so bad. The social stigma of being an , and the fact that I have always been considered a “weakling”, testifies to that. I desperately needed a friend. And cigarettes were it.

    Unless you are a drug addict, you cannot truly understand the horrors of dependency. It is not just physical, emotional or mental. It is a dictatorship that envelopes your world view, an aura that wraps pretty much every breath and step you take. I have seen too often, the demise of friends due to ...... or other addictive substances . The big difference with tobacco is that window of social acceptability is only now closing. From the point of society though, we will keep on going round in circles until we accept the damage caused by such substances and the reason people engage in such behaviours is to anaesthetise themselves, one way or another.

    I’ll be 59 this year. My daily blood oxygen levels are regularly around 89%. I recorded a 77% at one point, although I’ll put that down to error. What I will not put down to error is the fact that vaping has helped me breathe more easily. For COPD sufferers, that will be a great relief.

    I will share with you my experiences, and understanding. As to techniques, I can only offer you my personal experience. YMMV, and I am not a doctor. More to follow, but if you are to follow the path of vaping to deal with COPD, I would respectfully suggest looking a bit deeper. Nobody kills themselves without a reason.

  2. I'm a sucker for a good looking mod, and seeing the above discounted by 50% was hard to resist. First impressions were overall positive, an attractive zinc alloy and resin mod with a thoroughbred DNA chipset that was well balanced in the hand using either a single 18650 or 22700 cell. The fire button lighting up was a bonus, but seemed superfluous as this would be covered by your thumb 99% of the time. This feature is useful when charging in situ, the red glow gently pulsing rather than showing a plethora of colour in normal use.

    My first reservation was the overall finish. Despite being brand new in the original packing, there was a slight scratch on the paint next to one of the 4 main body screws. Not the end of the world, but a hint as to what was to be discovered later. The side decals were quite sharp and unfinished as well, not so sharp as to cut flesh, but ragged enough to catch any fluff from a pocket or lint from a cleaning cloth. The battery cover was extremely tight, and I just managed to unscrew it without having to resort to inserting a pair of needle nosed pliers into the 2 vents holes to turn it. After cleaning the threads on the body and the cover it was much better fit but still very tight.

    The size in length between an 18650 and a 22700 is accommodated with a removable plastic insert and adjusting the base screw on the battery door to take up the slack on the shorter cell. Again, this wasn't very well engineered, to get sufficient contact with my flat top 18650 I had to insert the screw just enough from the "wrong" side and manually tighten the cover until it made contact with the battery. Tightening the cover up manually to where I thought the end of travel was, and then adjusting the screw with a flat bladed screwdriver only resulted in the screw rattling around in the bottom of the mod. Thankfully, the base plate was connected to the negative of the battery casing, otherwise a serious short would have occurred. Saying that, if you put the battery in the wrong way ...

    In use, the DNA chipset was intuitive and easy to navigate. To get the most out of it, especially in TC mode, you really need the Escribe software. This is available for Windows, Mac and Linux, and the Beta version I downloaded worked perfectly with my stock Ubuntu install. This solved one problem I had under TC with this mod, in that even at 26W/220C, I could get the coil legs to mysteriously to glow and enter dry-hit hell. This was traced to a vicious pre-heat of 75W, once I had set that to a reasonable level, TC was a lot happier.

    After about a weeks use I was a bit disappointed with battery life even with 22700's. I've put this down to the TC anomaly, and I hope this has cured the problem long term. In Wattage mode, the battery life seemed OK and I could get ~ 8 hours of it at around 32W. Then disaster struck. I noticed an annoying rattle at the weekend, and was torn between sending it back or performing some surgery. For the benefit of ECF I decided to take the latter path.

    Tear down is straightforward, remove the battery cover, battery and atomiser and unscrew the 4 torx bolts. The U shaped resin side panel will then slide out from the metal frame. Holding the mod over a tray, I carefully did this as I wanted to know what foreign object was causing the rattle. Was it a stray piece of solder or worse? Sadly, it was the latter. I was concerned that a bit of solder rattling about could cause a short, but what I discovered was disappointing.

    The first thing I noticed was the battery positive connection was loose where it attached to the main resin body. On closer inspection, this was a lollipop shaped piece of metal that rested in a cutout in the main body. It was then attached by 3 screws, which held it down via a small round plastic plate with 3 x 1mm columns to help with location and orientation. That was the theory, anyway. What I found in reality was 2 of the screws were loose, and the rattling was a small shard of resin which I found in the tray (highlighted). Tighten up the screws and job was done or so you would think. On trying to tighten up the screws I realised whatever thread they were meant to tighten on was now stripped, so further investigation was required. The third screw tightened fine, and it wasn't until I removed the plastic disk I discovered why. 2 out of the 3 screw holes had splintered, and only 1 1mm screw was holding the battery contact in place.

    I was a bit surprised with this to say the least, but when I checked the side of the resin body, I was even more so. The 4 screws holding the case resin had brass inserts, whereas the most safety critical part of the device had no reinforcement. Granted, the screws were only 1mm or so in length, but why go to the trouble of reinforcing the case but not the battery contact assembly? To add insult to injury, the pip on the plastic disk did not locate in the undamaged hole as it was too narrow, so the insulation would not lay flat properly. Maybe the previously applied glue prevented this, it could be that the screws were meant to expand the columns of the disk to make a tight friction fit against the resin, but even then it is a very poor design. I wanted to solve a mystery though - why had the resin fractured? I hadn't dropped the mod, nor was I overzealous in tightening the battery up at any point. Where was the second piece of resin? Why had the loose battery connection not caused the mod to fail? Checking the space between the spring loaded 510 and the battery positive revealed another design issue - clearance. After reassembling the contact with liberal amounts of superglue to ensure the battery contact and screws stayed put, I added a piece of heat-resistant self-amalgamating tape (thickness 0.5mm) on top of the plastic disk, re-assembled and tested the device. I then took it apart again to see if any pressure had been placed on the tape. There was a clear indent where the base of 510 solder joint was pressing on the spongy tape. So another possible route for failure was revealed, apart from the obvious one that 2 out of the 3 screws were over tightened during manufacture. Extra long 510's on atty's could cause this mod to prematurely fail. More worrying though, the atomiser with a standard "short" 510 had effectively been holding the battery contact in place.

    Admittedly, the lower part of the 510 has a white mastic applied to it, and the plastic disk seems robust enough. However, if the atomiser gets too hot, there is potential for the insulation to fail, and under those circumstances the battery will be connected directly across the coil. The only way to disable this "permanently on" scenario is to unscrew the battery cover or remove the atomiser, not something you want to entertain with flames shooting out the top from burning cotton.

    I'm not sure where this leaves me concerning this mod. I really like it, and the DNA75 board is superb. It fits perfectly in my hand, and I even purchased a couple of extra 22700's to feed the beast. With the Nixon GR1 dripper, it is a great vape. As to how long it will last, especially taking into account the mechanical stress the wire on the bottom of the 510 will endure when changing atomisers, is another factor entirely. All mods suffer from this issue to a greater or lesser degree, as the bottom portion of the 510 has to move. Taking into account the lack of clearance, I suspect the GR1 was the only reason the mod didn't fail rather than the single solitary screw.

    On that basis, I can't really recommend this mod to an inexperienced vaper.

  3. Just a quick article on the benefits of flat wire for DIY coils. I’m not a huge fan on Claptons, I’ve never managed to get the right combination of size, material and temperature and generally found the resulting vape is too hot, the ramp times too high and if you use heavy gauge wire, they are cumbersome to form. I’ve tried a few pre-made versions as well, and my general impression has been “meh”. My best vaping to date has been simple 6-8 spaced coils, maybe at a push a twisted wire affair.

    Flat wire brings a lot to the vaping party. More surface area without a large increase in volume, the theory suggests you should find an increase in cloud and flavour. I spent this afternoon with a variety of commercial and DIY juices and a selection of drippers and a tank to find out.

    I used my Serpent Elevate, Oumier Wasp, a Hermetic and a clone Entheon to test for ease of coiling, flavour, cloud production and overall performance.

    My conclusions?
    • The increased surface area makes a substantial difference to vapour production and flavour.
    • Using both spaced and unspaced coils made little difference, I experienced no spitback from any of the configurations.
    • The Elevate and Hermetic which can be a bit "hit and miss" coiling, both showed a marked improvement in flavour. The Wasp didn't show any change, but the huge arflow may be the reason there. I hadn't really used the Entheon much prior to this test, but the results were excellent.
    • You seem to go through more juice with flat coils. The logic behind this is simple, more contact with a hot coil = more evaporation. Consequently, the vape production is more, although you can compensate for this by reducing the power used.
    • Temperature wise, I was really impressed by the improved performance without adding excessive heat to the vape. I could take my mod up to 70+ W before the vape started to get warmish hot. Pushing the temperature up to 100W I quickly found myself in dry hit territory, even with a very wet wick.

    Only 3 very minor criticisms:
    • The 510 was a bit "graunchy" with my Kylin. It's OK with the Dpro so hopefully it's cured itself
    • The silicon at the top edge is not glued down, if it got caught on a zip etc. it might split
    • The display is ever so slightly squint
    What I love:
    • Well balanced in right or left hand
    • Intuitive menu
    • I was concerned that the battery door might be flimsy, but it is well engineered
    • Colour matching red display
    • TC at 112 is superb
    • Tactile, clicky buttons
    • Built like a Sherman tank
    All typical OCD stuff. A great mod, which I would unreservedly recommend.
  6. Vaping is a strange business. Due to the subjective nature of the human psyche, what to the man or woman standing next to you might be greatest thing since sliced bread, could quite possibly leave you distinctly unimpressed. While there are lots of reviewers out there, there is also an awful lot of hype, vested interest and undoubtedly large piles of male bovine faecal matter. Being a particular, fussy type, these are my conclusions 6 months into my vaping journey, but more importantly, I’d like to share how you can - through the process of elimination - build a vaping setup that will make you smile from ear to ear and help you navigate through the vaping jungle of choice.

    Part of the problem is there are so many variables – vaping style, number of coils, coil design, wicking technique, wicking type, wattage, juice flavour/PG/VG ratios, airflow, drip tip design, glass size, battery condition and mod efficiency. Other factors - time of day, environmental temperature, your mood, or even what you’ve eaten or drunk recently can have a subtle (or not so subtle) impact on your conclusions. I’ve lost count of the number of times I have coiled and wicked a new atty, been distinctly unimpressed and after coming back a few weeks later, forming a different impression entirely.

    The key to all of this is to set a baseline reference point for your evaluation regime. Stick to it no matter how insane it might appear, and then tweak each of the variables until you reach a point where you feel you are getting more mileage. That way, you have a level playing field to compare against - there is absolutely no point trying to compare apples with paperclips unless you want to get frustrated. The parameters I use as a starting point to date are a simple coil (7 turns SS316L spaced on a 3mm former), Ruthless Dulche De Leche juice, Muji cotton wicks, fully open airflow and firing between 35-75 Watts.

    Finally, try and ascertain what type of vape you really like. For me it has got to be full flavoured, full bodied, warm but not wet with the more clouds the better. I don’t like restrictive draws, in fact too tight a draw makes me physically ill, so airflow may or may not play an important part in your assessment. The less air, the more flavour and the hotter the vape, so once again it is a compromise and subjective.

    Vaping style

    The attys covered in my conclusions are all DTL (Direct to Lung) devices. What is important though is developing and understanding your vaping style. Do you chain vape? Are you a “purger”? My vaping style has changed from my first tank (Aspire Cleito) which I was always purging, I now tend just to take a deep hit and frequently chain vape if the flavour speaks to me (or I enjoy the cloud formations).

    Number of coils

    I’ve settled on single coil (even for the Dead Rabbit) but not for the Loop. Clearly, you won’t get 2 coils in a single coil deck without some persuasion. Once you’ve got your baseline, then tweak and see if it makes a significant difference. Often, you’ll be surprised. The Kylin, while primarily a dual coiler, performs superbly as a single coil device.

    Coil design

    It’s simple coils for me, but if alien, gold plated twisted claptons are your thing, go for it. Some decks though are just not really designed for heavy builds, so your mileage may vary.

    Wicking technique

    I generally follow the rule of thumb tight in the coil, loose on the deck. Each deck will bring up it’s own wicking challenges, but you want that juice to flow easily to the coil. Too much (or indeed too little) wick and you will suffer from dry hits or a leaking tank.

    Wicking type

    To date I’ve used Muji, but having sampled some Rayon recently I’m a convert. It is longer lasting, cleaner tasting, and I suspect gives much better flavour as the coil is more saturated.


    For me the range is 35-75 Watts. To really test an atomiser, you need to put it through its paces over a wide range. Once you hit the sweet spot, and if you use SS or Ni coils, you can then use Temperature Control on your mod to dial in that wattage and you will never have a dry hit again (provided your upper temperature limit is not insane). Personally, I’d avoid using Titanium coils, they are dangerous if overheated, which you can easily do by accidentally having your mod in wattage mod with a high setting.

    Juice flavour/PG/VG ratios

    Totally subjective, the only agreement is lower VG juices may carry more flavour at the expense of giving you a harsher throat hit. This will also effect cloud production, but we are not doing this for the theatrics, honest. Pick your favourite and go with it.


    While you can try and rationalise the amount of air in each test, due to differing size of airflow vents on different devices this is difficult to achieve in reality. I go for wide open, and go from there.

    Drip tip design

    Often overlooked, the internal diameter, shape and length of a drip tip will make a considerable difference to the taste and temperature of your vape. The stock drip tips supplied are generally pretty good, with a few exceptions. Often, you can change these, but sometimes you can’t and will just have to live with the manufacturers offering.

    Glass size

    Makes a surprising difference. Could be down to the air pressure inside the tank or other variables, but for me the smaller glasses rather than the bubble sized ones give the best flavour at the expense of juice quantity. It might just be me conflating small size with better flavour, though.

    Battery condition

    Only use fully charged batteries for testing, your flavour will drop off as the charge decreases.

    Mod efficiency

    Different mods deliver different power, some have High power modes, some variable temperature curves, some nothing at all. Be consistent and use the same mod on the same settings for your evaluations.


    Ratings and opinions are purely my own, and I've tried to be as fair, objective and honest about my experiences as I can. Yes, of course, feel free to disagree, and comment.

    Behemoth tanks

    You will never get the same flavour from a tank as a decent dripper/squonker, but you can get pretty close.

    Kylin II

    Ease of use 8.0
    Durability 8.0
    Flavour 9.0
    Airflow 9.0
    Shineyitis appeal 9.0

    Not a flawless tank by any means, the refill cap and airflow are very stiff and if you are a new vaper, dual coiling this without having a dangerous short may prove a challenge with bigger 3.5mm coils. The wicking (especially in dual coil mode) is fussy, get it wrong and you will get a serious dry hit. It doesn't leak, but it is definitely “damp” in use. Flavour wise, it is unsurpassed in my collection at the time of writing.

    Wotofo Serpent Elevate

    Durability 8.5
    Flavour 7.5

    Shineyitis appeal 7.0

    This tank just edges it over the DR on design. Like the DR, it is a pig to wick and coil to get the best out of it (keep the coil as low as possible). Again like the DR, it seems pretty leakproof. Unlike the DR, if you purge the tank you will not get a face-full of hot vape. The 2ml TPD complaint plastic reservoir is as functional as chocolate teapot. Flavour wise, it is not bad at all, and although the Kylin gives it a kicking, it is still a great tank. It took a couple of attempts at setting this up for best performance, and how it performs with chunky coils remains to be seen, but I suspect it will come into it’s own here.

    Dead Rabbit RTA

    Durability 7.5
    Flavour 7.5

    Shineyitis appeal 9.0

    The best analogy I can use for this tank is to compare it to an ageing, classic sports car. Temperamental, coil height and wicking have got to be just right or you will suffer one way or another. It also has very bad manners, giving you a dose of hot vape if you accidentally purge the tank unawares. You also can’t assemble this when the deck is screwed into the mod. Get the sweet spot though, and this tank makes for a darned good vape and makes all the effort worthwhile.

    Aspire Cleito / Cleito 120 rebuildable

    With the stock coils, these are excellent tanks. With rebuildable decks, it is another matter entirely. The build quality is not brilliant - the coil posts lean at an angle due to the insulating material and I stripped an allen screw and I am not Mike Tyson. Vaping is a bit harsh and hot, even with the temperature scaled down. You will also need to buy a separate bubble glass if you want to use the conversion kit. You are also limited to custom Aspire drip tip. A great tank if you are happy buying stock coils, if you are looking for a rebuildable there are better choices out there. Design and style-wise, the market has moved on.

    Aspire make innovative products, and this is one of their best. A convertible RTA/RDA with a squonk option, this piece of kit got me hooked on dripping then squonking. Finish isn’t great, the tank isn’t going to win any awards for flavour if compared to the Kylin, but due to sentimental value, you can claw this piece of kit from my cold, dead hands.

    Dainty Drippers / Squonkers

    I just love 22mm flavour bangers. My latest vaping obsession. If your after flavour, look no further. Anything lager than that, and you are into the arena of diminishing returns.

    Shineyitis appeal 9.5

    If you are after 100% flavour, this is the atty for you. It is the Deux Chevaux of drippers/squonkers – functional, quirky and incredible value. There is an RTA version available, with a 2ml tank. Don’t bother, it is a pig to fill, by the time you have inhaled sufficient nicotine to restore your sanity, it will be refill time again. The only way I can see Oumier improving the design is coming out with a stainless steel cap and having 4 rather than 2 post screws so you can install LH and RH wound coils. Trifling matters though, this is a classic piece of vape kit. Some have people report spitback, but if you wick the coil tight enough, you shouldn't suffer this. At a push, you can add a custom 510 drip tip, but this defeats the object. The whole beauty of the design is your mouth is close to the action. Unlike the Nixon, while the tip is a small diameter, there is sufficient depth to cover it with your lips.

    Coilart Dpro Mini

    Not quite a flavoursome as the Wasp, but a lovely vape all the same. Beats the Wasp on build quality, this is more high-end executive car than farmers runabout, only let down by the slight lack of flavour. The 3 drip tips supplied compensate for this to a degree, or you could always add you own.

    Hadalay (clone)

    Appalling build quality, I had to clear out metal swarf from the air vent (that I could have easily inhaled) before use. Flavour wise, it is up there with the Wasp most of the time. I’d love to buy a genuine version, but am hard pressed to reconcile paying 4 times the price of the Wasp for virtually the same performance. I do prefer the stainless steel cap with removable drip tip, though.

    Shineyitis appeal 9.0

    I have a love-hate relationship with this atty. I love the overall look and the design of the deck, and the build quality is very high indeed. What lets it down is the lilliputian drip tip, the airflow noise, and the flavour. Maybe my lips are the wrong shape, but the drip tip is just far too shallow. Yes you can replace it, but as the cap is so thin you have to be careful you don’t end up burning your tip on the coil if it is too long. Flavour wise it is very consistent across juices, and it is not flavourless by any means, it just hasn’t got the range and the “in your face” attitude of the Wasp.

    Beautiful build quality, only let down by the 3 O-rings that keep the cap clamped on as tight as aeroplane wings glued on with Araldite (which indeed they are). It also uses a proprietary clamp design to hold the coil in place. Flavour wise, nothing to write home about compared to a 22mm, but I suspect to get the best from this you need a heavyweight coil, something I will try at a later date.

    Another well built atty, the flavour is OK if you get the coils in the right place. You can single coil this, but as the coil will be outside the airflow and close to your lips, the experience will not necessarily be pleasant. The unique “W” airflow design seems to be a case of form over function, and the Wasp, with a much simpler arrangement annihilates it. I do like the look and feel of it though, and it will probably take a lot more punishment than the Wasp if dropped.

    Hugsvape Ringlord

    Shineyitis appeal 9.5

    Why I bought this atty I don’t know. Well actually, I do. It looks phenomenal, and the concept of forcing the airflow over the top of the coil teases you with innovation and great performance. In reality, what you get is something akin to a noisy wet, over friendly dog that vaguely smells. I’m probably being a bit harsh here, with a larger coil to support the huge air chamber, it might come into it’s own - once you work out how to trim the leads to the right length. It is essential to stop coil from shorting on the airflow bridge, which requires a lot of trial and error. No way is this a stealth vape device, either from looks, cloud output or the sound it makes – especially the sound of glass smashing if you drop it on the floor. More novel than functional, the biggest appeal is its design, the worst feature the vape experience.
