I have to side with teabagger, and this from someone that has spent well over $1000 this month alone on vaping with out complaint. At what point do we call foul, these are not complex machines, they are battery sleeves. Granted you have to thread a few parts, something any 10th grader in metal class can do, but for the most part this aint rocket science, well unless the gasses build up from lack of vent hole.
All I am saying is that I bought a netbook for my kid the other day for $250, that had to be more complicated to build then this flashlight with a plug in. Now if they had personalized it, or made each one differant and sold it as art then maybe. But for that price i could hire a midget to walk around with me and blow vaper in my face.
