Sent the defective mod back to Vaportek Monday and received a replacement in Saturdays vapemail. I call that fast service. They have done right by me on preorders and quite admirably with a replacement device that works incredible. I am thoroughly impressed with the iPV v2 performance. It has the DNA30 board whipped. The power comes super fast. Ability to go lower resistance than I dare. Well after a 24ga. build I will let you know. Seems Vaportek caught some bad rap earlier in the thread. In some ways I can understand their frustration. They have done a tremendous job of bringing some incredible devices . Priced righteously and are cutting edge of whats been available. Just my two cents on dealing with them. The problem I have with them is offering so much new stuff that you want another and another new mod. I have two dna20, two dna30, and now a sx-330. I'll have to get an sx-350 and a dual 18650 mod next. Maybe one with both features. Vapedom is expanding rapidly and is anything but boring. Its great to know lives are being changed and possibly saved along the way. The ECF has given me so much more than just information on vaping. Support from members is phenomenal and on a global level to boot. Our voice can now be heard as one and maybe the big bad wolf will get winded blowing down a house made of stone, back-up batteries, wire and cotton. Happy Vaping Folks!
