I won an MVP in a raffle. Came with 2 iClear 16 clearos, which worked great. The Kanger Protank looks stunning on the MVP, but my favorite clearo to date is the iClear 30. I've got four of them and not had any issues. The draw is perfect, I love the Knucklehead driptip. If the clearo was pyrex, it would be perfect.
I got at least 2 days between charging on the MVP. It can be somewhat easy to turn the MVP (version 1) off accidentally because of the nature of the fire button, but I understand this has been fixed in version 2. I also had a problem with my cartotanks not working on the MVP, but it was a connector issue the the carto, not the MVP.
I ended up loaning the MVP out to a close friend interested in making the switch from cigarettes to vaping. If unsuccessful, I get the MVP back. Prior to that, I used the MVP alongside my Provari. I actually miss it. I'm still using my Mini Provari.
