I got the Vamo over the mvp, it was a mistake. I knew my first mod would just be a stepping stone and trial no smoking run and that if I succeeded in the transition I'd get something nicer so I didn't sweat it too much. You need a backup anyway right? The VAMO did it's job, and had no functional issues though.
Well, I wish I had the mvp over the vamo. Now that being said all my batteries and charger are still used daily so that was a pro. MVP's a better quality mod and has some nice bells and whistles (puff count, phone chargers work, can charge a phone). If the 33 hz thing matter's then the mvp does it the better way...if it matters. Plenty of wraps out there to personalize (R2D2 wrap is banging). I was initially turned off by box mods but i have changed my mind. I don't have an opinion on the VTR so I'm not commenting on that.
34 days smoke free!!! No worries about going back. I'm done with that poison.
