I would also recommend the MVP2. Great device! If it's too large though, (it's smaller then it looks online, I promise you) then go for the iTaste VV v3. Does everything the MVP2 does, except for charge your cell phone. Both are great to learn about different features and both provide a nice vape. Also, if you want better taste but don't want to rebuild, I highly recommend carto tanks. It take a little time to properly fill and prime the carto, but once you do I think they take less time overall to maintain. All you'll have to do is top off the tank until you get a burnt taste from the carto, which doesn't happen for quite a while depending on your juice. I've put on average 30 ml through mine before feeling like they need changing. After that, I just toss the carto. No dry burning! Way better taste then clearos
