I've been using the ipv mini 2 exclusively for a couple weeks now and I must say I love it! Coming off of cloud chasing .2 ohms on a mech I was kinda worried 70W wouldnt be enough but I've been rockin .5 ohm coils at 40W and thats producing more than enough vapor for my liking. Only problem so far is the battery cap is very cheaply made. Lots of people saying they stripped the threads by dropping it once. Buuuttt, looky what i just found IPV Mini Replacement Battery Caps
