Couldn't be happier. I opted for the voltage display and am running a DCT tank @ 1.5ohms and getting better vapor and flavor than with my Provari at 3.8v. The voltage display is accurate to 2 decimal places. It's a little bit of a pain to adjust it as you have to flip open the tin and turn a small wheel, but I've only had to set it once. I'm nitpicking now to be honest as I can't really find anything else to complain about. It's very well made. I've been using Jammin 24ml juice from V4L. If anyone has any specific questions, please feel free to ask. There is a great review that someone else did in another area of this site that I read a few weeks ago, so I thought I would give this a try and I'm very pleased. I've been using it constantly for 24 hours now and it's easily my favorite mod.
