I bought an Innokin iTaste 3.0 VV back in November, it was my 1st kit and on the onset was very happy. I moved onto an MVP within a few weeks and the girlfriend kept the original purchase.
Now, 6 months on, the iTaste VV 3.0 has had it, not very impressed to be honest.
It only really lasted 8 hours max before a complete recharge was required but after a couple of months this reduced and has been reducing ever since. It now won't take a charge at all and the bottom comes off if you're not careful when disconnecting the charging lead. We weren't fortunate enough to get the one with the extra rivets that apparently addressed this issue.
Now on the hunt for a replacement, won't be buying another one of these.
Will probably go for an 1100mAh batt, possibly 2 so there's always a spare handy, but she does like the puff counter and V W, not interested in the V V.
As for the MVP, still working great and I charge every couple of days.
