You guys were not kidding when you said the build quality of this thing was very solid. I swear I could run over it with my truck and it would be fine. However, this leads to my only rub with this device, weight! I am having a hard time getting over how heavy this thing is. It is my first box mod though so I guess this is normal. Other than that, it is the nicest piece of ecig kit I've ever owned and it's not close. All of my other battery mods will go up for sale. I can't imagine buying anything else unless they come out with a SX Mini LITE version made of carbon or something.....Ha Anyway I too would like to thank Techno and Retrox for their input to this thread. They got me off the fence and into an awesome device. Don't think about it, just get one!!
