I like my IPV2. 50 watts is enough to make my coils glow. I have several different attys from 1.4 ohm kayfun builds to .5 ohm dual magma builds and they all vape wonderfully on my IPV. I also like its a single battery unit.
I just wish I could get the threading out of the box to replace with magnets, tried and bent the screw some so I quit, other than that well spent money on the IPV2
