I've had mine for about three days, and really like it. Battery life is amazing! I've been vaping heavy for two full days, plus about three hours this morning, and still showing green light! (Yellow indicating low charge, Red indicating you better charge this sucker fast)
My biggest complaint is no ohm reading! I have to remove my tank from the MVP, and put it on my Gripper, or some other device, if I want/need to know what ohm it's at.
I'd also like to know how much charge is left! Again, comparing it to the less expensive Gripper, the Gripper shows me 4.1, 3.8, 3.4... whatever volts remain in the battery!
I'm going to a basketball game tonight. I'd like to continue to see just how long the MVP lasts me, and not recharge before the game if it still indicates green, but I could leave the house for the game and the MVP shows a green light, and ten minutes into my drive to the game, it suddenly shows me yellow! 30 minutes later (I honestly don't know how quickly it goes from yellow to red) it may show red, and suddenly, I'm away from home with hours until I return, with a dead PV.
NOT a big deal, as I guess I'll just recharge each night.
Also wish it had full range of voltage, from 3.0 to 6.0, but again, not a deal breaker. I generally vape at 4.4-4.7.
Wish they'd lose the puff counter. What a useless feature!
