    Default The reason why Blu cigs have problems, and how to alleviate them as a user.

    E-cigs are pretty poorly engineered. The first one I bought was the 51 duo. You'll notice that all e-cigs have two small holes either in the atomizer (3 piece models) or on the battery fringe that connects to the cartomizer (2 piece models).

    Those holes are there to allow air to be drawn through the atomizer. The air coming through the battery is extremely minimal compared to the amount that will come through those holes. On most e cigs, those holes get covered up by something and basically don't function. The 51 Duo doesn't work at all if you tighten the cartridge down really tight, but ease it off a bit and it starts working very well.

    Most people think air needs to be drawn through the battery to activate the pressure switch, but that isn't the case. The venturi effect ensures that the pressure switch is activated by the low pressure zone created across the atomizer when air is quickly drawn through.

    The Blu cigs e-cig attempted to address that problem. That's why there's little slots cut out of the battery fringe that aren't there on other e-cigs.

    But, they're still using the same atomizer... which was tested and designed in e-cigs that DIDN'T have those grooves. Hence, the atomizer does not function ideally because they fixed the problem too well. The holes in the atomizer are too big when you actually open them to the air properly. Another consequence of the venturi effect is that drawing air faster decreases the temperature more.

    A second problem is how the atomizer itself seems to work. It requires pressure to draw liquid onto the element. Since the flow is extremely unrestricted, you have to breathe in HARD to create enough pressure for the atomizer to work properly.

    So I'll write up a little guide to using them that should improve the results people get:

    1) After inserting a fresh cartridge, twist the battery and atomizer clockwise while keeping the cartridge still. Then withdraw the atomizer from the cartridge and clear all foil/plastic from the atomizer and look down into the cart to make sure there's nothing in there. The foil stops the atomizer from working right if it's in there.

    2) Always store your ecig in the pack, with the LED facing down. This helps you get the full amount out of the cartridges. I also recommend having both atomizers in the pack (set into a cartridge) so you can rotate through them to get a more consistent smoke and get the maximum liquid from the cartridges. A cartridge with an atomizer in it will fit in the normal cartridge spots in the blu pack.

    3) Breathe hard. REALLY hard; you need to breathe in fast enough to where you're creating suction pressure. To reduce how fast you need to breathe in you could try plugging some of those grooves on the battery; either permanently, or just with your fingers while taking a drag. This will reduce how much effort you have to expend to get a good draw.


    The blu cig is definitely not a huge vapor producer. However, it seems fine for smoking replacement. The vapor is about as much as a cigarette gives off, and you definitely get the right amount of nicotine. Keep in mind that the only vapor you really see is the propylene glycol; an INACTIVE ingredient. I'm guessing because the blu carts are so small they reduced the amount of PG.

    Both of these suggestions run counter to my personal experience. Well, actually, I should clarify that: I did store the blu LED-down until I switched to different filler material that wicked better, as well as thinner liquid, so now I store it LED-up so that I don't flood the atomizer. With the standard carts, though, I agree, LED-down makes more sense.

    But as for the breathing hard stuff, drawing hard on a blu activates the battery but produces NO vapor. I just tried, and confirm this. Light, slow draws-- just hard enough to activate the battery and keep it on-- produce a LOT of vapor. Again, this is in my personal experience after two months with the kit.

    You're definitely right about covering one or more of the air intake holes; that produces a heavier draw, more vapor, and a higher atomizer temperature (which may or may not be bad for the atomizer, but I haven't killed one yet).

    You're not breathing hard enough. I'm serious. Breathe in with everything you've got; your cheeks should suck in from the pressure.

    Slow draws work great when the cartridge is fresh and the atomizer is basically flooded with liquid, but they don't work at all once the cartridge runs down a bit which is why people think they can only get 10-12 good draws from a cart.

    I swear, I am. Almost absolutely nothing-- the teeniest visible puff of vapor. This is with a full cart. And I can say with total certainty that hard draws have never yielded any vapor with my blu kit since I got it two months ago. If you don't believe me, I suppose I can post a video, but I'll look really funny almost collapsing my lungs on this thing.

    Long, slow, even, LIGHT draws have always worked better for me-- for the first three days when I used the stock carts, for the month I used the stock filling and Johnson Creek liquid, and for the month since I've switched to PET filling from Lipton Pyramid tea bags. Maybe my equipment's anomalous, I don't know.

    I get what you're saying about getting the last bit of juice out of the bottom of the cart by drawing harder, though. I guess that hasn't been an issue for me, because the JC liquid is quite thin and wicks well, and with the PET, I can empty out a cartridge without even trying. I still have some old carts with the polyfill, maybe I'll do some experimenting.

    I just ordered my blu, would it be easier just to cancel and find a diffrent model??

    Sorry, but your theory is proven wrong here on the forum.

    While you have to draw hard on say an M401, or fairly hard on a 510, the Blu actually requires a smooth, fairly light, long draw.

    Hitting it hard as you instruct does two bad things:

    1) It heats up the atty too fast, giving a harsh, hot vape

    2) It makes you hit the batt cutoff way too fast (3-4 seconds in many cases)

    A smooth, light and long/consistent draw will allow you to draw for much longer (I can get 7 seconds before cutoff) and more flavor without any harshness.

    The Blu has the easiest draw of any e-cig or PV that I own, and I have had my Blu for a while. Same goes for my Sidesho which essentially is a Blu with a longer battery.

    One trick you can use if you experience a tight draw (which you should not, the Blu draws like an open/empty straw actually) is to slightly loosen the connection between the batt and the atty. This trick is used on most e-cigs. It allows more airflow.

    If ypu're experiencing a tight draw, you might have foil on the atty as well. When popping a carton always twist it 360 degrees, then remove the cart. There should (90% of the time) be the foil ON the atty bridge. Remove it and put the cart back on and vape away.

    All depends on what you need. In my experience, the work you might want to put into making the blu work better is exactly the same sort of stuff you HAVE to do with most other e-cigs: stuffing and filling carts, cleaning atomizers, etc. I doubt you'd have an "easier" time with a 510, for instance, and depending on the kind of smoker you are, you might have more trouble with it because it's bigger, heavier, uses a manual battery, etc.

    One benefit of the blu is that they have a 30-day money-back guarantee, which I don't think I've seen for any other e-cig. So since you've already ordered it, you may as well try it, in my opinion. You might like it. I do.

    The Blu is a good unit, great for a lot of people. I always tell people that if they are a HEAVY smoker, then the Blu might not be entirely satisfying because you may want more vapor production (feeling of "smoke" entering/exiting body) than the Blu can provide.

    IF that happens to be the case, return the Blu and buy a Sidesho. It is essentially a Blu with longer battery and better carts (more juice) that gives a load more flavor and vapor. It is 99% as convenient as the Blu using the same style charging case, the only exception being that you cannot carry an ASSEMBLED unit in it (like all other e-cigs actually).

    If you aren't as hung up on the convenience, the 510 is about the best all-around for beginners and pros. Mountains of vapor, tons of flavor.

    See my Sidesho review and comparison to Blu in the ModernVapor forum in the vendors section.

    i would have to wonder if Blu is getting feedback on the problems people have with the foil wrapped cart. you would think that if they are then they would be considering changing the design to match that of other ecigs such as the sidesho, seeing as how its the same manufacturer.

    as it is, im fairly happy with my blu even having been a pack a day smoker. the throat hit and amount of vapor are enough to satisfy me, though the carts dont last as long as i would like, or as blu claims...once i actually run all my stock carts down im going to play with the PTB mod and and some of hxj's other suggestions for refilling the stock carts...

    Can anyone recommend a reliable quick nicquid supplier in the states? there are no local suppliers where i am at.

    The Sidesho does use foil-sealed carts like the blu. Modern Vapor kindly sent me some to test with the blu equipment, and they don't fit (though the mouthpieces do).

    As for liquids, I'm still a big fan of Johnson Creek. Their reduced-PG formula seems to work really well at the blu's atomizer temperature. I saw a definite increase in performance once I started refilling with JC instead of using blu's stock prefilled liquid. Their delivery time is decent (usually ship within a couple of days, and then it's up to the USPS) and they have a 60-day satisfaction guarantee, which includes shipping both ways. They cover it all. Be aware, though, that their flavors don't agree with everyone (weirdly, several people seems to think the base flavor tastes of bacon, which I don't see, but I'd probably love that!), so I'd suggest getting the sampler pack (10 flavors for $21.95 plus shipping) and seeing which, if any, you like. I'm a huge fan of both the JC Original and the Tennesee Cured, and I love the Summer Peach when I'm in the mood for something more fruity.

    JC fluids can be a little thin, and last night I mixed in about 1/4 of ECOpure Gold. ECOpure is a vegetable glycerine-based, stripped-down, pure-as-possible liquid made in the UK. This thickened up the JC a bit, added quite a bit more vapor, and didn't blanch out the flavor much at all, so I'm very pleased with it. ECOpure is available in the states from InnoVapor and Cignot and presumably a few other places, but those are the ones I know. Cignot probably ships faster than InnoVapor.
