I won't do it Bad I can't say something is good when I had a lot of the issues happen to me. This thing isn't what ismoka claimed it would be and they will not back up their product. I stopped using mine before it got dangerous. Ismoka just put 4 pretty new finishes on the 30w and my wife wants one. I'm just not sure,these cheap mods bit me one too many times. She has my VS 30w and loves it, she just wants something pretty to carry. Tried to get her to pick a jwrap or a different colored shark skin, but who know with that woman lol. I spent $154 for 2 mods the 30w for her and the rDNA 40 for me. The final mod I ordered today was an IPV 4 for $65 and I'm officially done. I have a back up board for the rDNA new in the box and I wanted to try the YIHI and liked the dual 18650's everything else is a bonus.
