When I quit in February I did so using the vv3.0 and the MVP2. I love those things, and am very grateful for their ease of use. I tried a plethora of "high end" clearos and ended up sticking with Kanger T3S clearos which are a good trade off of value and quality (about $3.50 a pop at FT).
I know there's a lot of love for the MVP, but after a while I stopped using it and exclusively used the itastevv 3.0. Battery life is not an issue, I'm a white-collar schmuck so I can always charge at work (while working). The performance is identical. So my primary vv device is the itaste 3.0. I still use one every day. I "loaned" the MVP to my brother in the spring, he's been smoke free since. I would consider myself a compulsive hobbyist so it was not long before I got into mods and coil-building, which I'm knee-deep in now. I use RDAs at home and sometimes at the office and itaste3.0s "on the go".
If I wasn't a compulsive hobbyist I would be satisfied using the vv3 for the rest of my days. Alas, that's not how my brain works.
