mvp v2 was my first vaping battery and doesn't get the love it deserves now as I've gone over to the mech side, but I will never sell it it's just too good to have handy (if and when you go mech you'll find it useful as a resistance checker on your coils too ).
Agree with everyone here, the MVP is a cracking bit of kit, however, DO NOT buy the VTR, because if you do, the MVP will end up tucked away and forgotten about!
Seriously though, they are both excellent, and both of them perform exceptionally well, i am glad i have both, even though the MVP is relegated to my day bag as a backup.
Currently vaping Darkstar forest fruits in a Kanger Aerotank at 8.5 watts, loads of vapour and flavour and really consistent, literally cant fault this at all!!
I ordered my MVP from fattech and I is still waiting. 1 week off of the analogues wish i had found this forum before I went to the clean side so could have had my shinies sooner
