I have been using one of these for just over a week. I purchased one when they were first advertised @ FT. Pics from Fasttech I am using a 0.5 ohm ceramic coil that came with the tank and purchased another as back up. This is said to be best at between 30 to 50 watts , so at first I started at 10w Hmm nothing so kept on notching it up and it started to shine at 40w I have been sitting at 45w all week and it's pretty damn good ( not that I am keen on vaping at that level ) To me at 50w it was too warm but others will no doubt enjoy this . I have had no leaks what so ever , it is very easy to fill ( same as Subtank Minis ) Today I took it apart cleaned it all up ,washed out the ceramic coil and dry burned it 3 or 4 times in short bursts. It gave off the smell of the flavor I have been using in it and was not unpleasant. I refilled it left it a few minutes and it is as good as new.So it does take a dry burn but I was reasonably gentle on it as unsure. The instructions that came with mine may as well have been missing . The only thing I do not like about this tank is it's only 3ml and at 40w it's a wee bit thirsty- as to be expected ! Would I recommend this to vapers , yes no probs at all if you like vaping at 40w to 50w . I can not compare to other ceramic vapes as this is the one and only for me. Is it any better than what I normally use ? (Subtank Minis and KFs) yes but there is not much in it to me.
