I'm absolutely ...... with the B&M I purchased my sx m from. 1 month ago, I went to them and inform them on the paint issue and they agree to replace but was out of stock. They just managed to restock the mod and I paid a visit to them and now they refuse to replace it saying it's not an issue. I showed them my email conversation with yihi on this and they change their statement saying they only replace within 7 days of purchase. Sigh...I'm sending a complain to yihi on this particular vendor.
Yeah, definitely never buy from them. If you contact YiHi about it, I'm sure they can setup a warranty replacement through another vendor though.
For sure I'll not go there again. If they say no from the start, I wouldn't be as ...... as I am now.
I want one really bad... But $199 will be the most I've ever spent on a device. And its Chinese.
Someone convince me that I'll save enough money on temp controlled atty's to justify it. I go through an Atlantis atty every 3 days.
Or if someone would clone the M class, I may be happy with that. I feel bad buying an American device that's been cloned, but the Chinese manufacturers deserve it.

OK - Danny,
I took your first paragraph a little insulting. I am fairly well versed in electronics for one and not only did I suggest googling the subject I also gave a link that put the answer in layman's terms. To suggest that I don't have the proper facts takes a real leap on your part I have been working in the electrical engineering field for over fifty years. Now that the casual insult is out of the way...
I would still like to direct you to look up information regarding the advantages of putting batteries in series. It can be relatively simple or if you feel like digging it can also get very technical very fast. Putting the batteries in series is only done to be capable of outputting the the claimed wattage. With one battery you do not have enough voltage to out put 150/200 watts into the coil. That is the only reason it is done. Again if you found my suggestion to look the subject up if you did the searches you said and have yet to come up with a satisfactory solution can you imaging how long this post would get if I tried to explain a topic that the professional Tech Writers have trouble with some of these topics.
As far as the series batteries being used in a Mod, flashlight, or whatever has absolutely nothing to do with the underlying electrical principles. The batteries have absolutely no idea what they are putting power to nor does the principles that govern series vs parallel operation care.
A fact is that using batteries in series is of no advantage whatsoever if you are driving the same coil you used on your SXmini at lets say 20 watts. Yes your are still providing 20 watts from the two series batteries and yes at a half the amperage but at twice the voltage. To the coil you provide half the amperage and twice the voltage from the the DC to DC converter. Amps X Volts = wattage i.e. nothing has changed. Two batteries in series act like one higher voltage battery with the same mAh as a single battery. Tow batteries in parallel act like one battery with twice the current capability (or twice the mAh capability). I am not a Tech Writer so if this sounds convoluted then I will suggest again you do your best to look up an explanation that makes sense to you. If you choose to believe this is some kind of cop-out on my part because I don't have the background and knowledge to say what I am saying I would suggest you check my on-line profile to determine what I may and may not know that is your privilege.
This post is already quite long and I am very sure I have not convinced you of anything. Which is why I said I would rather not debate this. There are two things working against us 1) Everyone that bought the unit because it has two batteries and believed it will give them better battery life will not want to believe what I am saying; 2) Unless one is willing to search and study the subject and determine the electrical principles involved all the online debates will only confuse the issue and probably start a "Donnybrook".
I will close by telling you I will search this issue in an attempt to find a reasonable explanation by folks that write technical articles for a living.
I strongly disagree with the last statement.
Chinese manufacturers have the potential to build with equal quality as manufacturers from any other country. So why do they get a bad rap? Because to get that quality, you would pay as much as you would for something made in another country. China also has the unique advantage to produce items for pennies on the dollar comparatively, and that manufacturing is what people gravitate toward-- in other words, it's why you see so much more of it: people want it cheap!
It's no secret that China leads the world in math testing scores. With that, it only follows that the potential for good engineers is also there. Again, the "WalMart mentality" drives the over saturation of the market place with cheaply made, substandard quality, and reverse engineered (aka "cloned" or better termed "counterfeit") products.
The SX mini is a prime example of top notch engineering and manufacturing. Even John the lead engineer for Evolv commends how well the SX350 board is designed. One look at the SX Mini, and it's easy to see a device that is built as well (and arguably better) than some devices made in the U.S., Germany and other places. You also see a level of customer support that rivals anyone else.
Chinese made products, as with products made elsewhere, if you eliminate the hype factor (I.e. High demand driving prices up), you will get what you paid for.
It has been cloned with no temp control... Look around the forums, there's a thread on it

Quantum, The problem is if you are applying 20 watts to the same coil that you were using at 20 watts with a single battery device you are also pulling 20 watts from the series batteries. Nothing is free. The higher voltage is only required to obtain the the higher wattage they claim the unit is capable of. If you are not running above 50-60 watts the second battery is just along for the ride.
You can not have mAh without voltage. So whatever the wattage is in the coil that is the wattage being pulled from the batteries.
Gosh I hate this - mark my words unless someone finds an appropriate document explaining this phenomenon the debate will go on for ever.
I gotta wait then or u gotta pay to playYeah... But I want the temp control.

I hope John studied the SX 350 in great depth. It would definitely help before the next device is brought to market.

Argh gotcha
the bit that is confusing me is the lower amperage being drawn to meet the required volts/watts
If your doubling the voltage would this not half the amperage & wattage being drawn from the batteries to supply the same 20w
am not saying your wrong far from it as I am not as qualified on the subject as yourself
just struggling to understand mate

Actually no the statement is correct but the implied results are wrong.
The only real way to think of this is Watts in is equal to watts out. If you increase the voltage then you have to decrease the current to maintain the same wattage across the same resistance which you can't do. The voltage across the coil is a equal to the V-applied (times) the current flow so if either change the wattage will not be 20 watts.
If you use the same coil as you did with a single battery at 20 watts and then put the same coil in a series batter unit and double the voltage you will double the wattage. Besides with the series battery units you don't have the option to set the voltage out to the coil. You select 20 watts which by definition means you are really applying the same voltage and current to the coil if the coil has the same resistance. Amps X Voltage = wattage. Wattage is the power being drawn from the batteries
If they could produce products of the same quality as other countries, why don't they? My hypotheses is that the cheap labor allows them to build three to get one right.
My industry is a bit different then e-cigs, but the Chinese product is bottom of the barrel. They are great at mass production, but not making a lasting product. They are willing to replace but not improve.
Many industries began before the industrial revolution. At that time, building something well was a must. It would take too much time to build another if the first went bad. China didn't experience that. They bought the machines to stamp out the products. So they came into the business in a different way. They need to limit the amount of metal in an item, or limit the amount of labor. Or use cheaper metal.
One example with the SX mini is the finish... Why not use a more durable finish? That's one consistency I've seen in Chinese anodizing/finishing. It's constantly bad.
Now, it's very unlikely an American company could make it cheaper. But, I can guarantee they could make it better. The problem is that once they do they Chinese will knock it off and sell a clone. That's why they deserve the same.
PS - I am going searching a professional explanation. Any trouble you have digesting this is totally overshadowed by my inability to properly explain it.
.
This is where I am going wrong then as I am seeing half amperage & expecting half wattage to be drawn
