One week in with my mine and all good so far.
It's comfortable, well built and very small considering it has three 18650s. I run an RDA on it at 68 watts and I get days of battery life which is awesome for a mod that's smaller than most two or even some single battery mods.
The only bit that concerns me is the screen which feels like it would not survive a good drop.
The issues with heat are directly related to it's size, some people really want their cake and to be able to eat it. If you really have run at 100 + watts then get a bulkier mod to absorb and dissipate the heat.
I got mine for $42 delivered which is a bargain. I would recommend it to any VW user frustrated by short battery run times, and doesn't mind a meaty heft.
As I understand there are issues with TC, but I don't care because I don't use it.
Anthony Vapes attributes the poor TC performance the decision to ground through the body rather than a dedicated wire from the 510. I would imagine that this was done for pricing reasons as the later requires additional manual assembly. Remember this is a CHEAP mod (cake again). Even though TC is now a relatively mature tech and is included with virtually every mod, it is still a finicky technology not well suited to budget equipment.
Smok and others would have you believe you can have a mod that looks great, lasts forever, does everything including 1.21 Gigawatts and costs pennies. The real world does not function like that.
