I've about nic'd myself to death tonight trying this new toy out on every tank and clearo I have......everything is great on it. I'm a low wattage vaper....got it set at 4.5 with a 2.1 coil on my ADV am I really like it. I would like the button to be Spring loaded as others have mentioned, but so far no problems. Great vapor and flavor and the battery life is gonna be awesome next to my Provari and my Vv3's......very happy. Got another coming in a co-op at half the price I paid for this one.....wish I had ordered a couple more. Will see what version 2 offers. Great device for sure. Got mine in 3 days from Indy Vapor.....fast shipping and full kit with 10% discount.
