I own two Provari's and could easily get by without another mod. Visiting my local B & M I noticed the sales staff were all vaping either a RDA on a mechanical or using an MVP. I wondered what the appeal for the MVP was, too. Then I won my own MVP in a raffle drawing. NOW I GET IT.
This little unit is extremely versatile. It is pocket-friendly, durably built, light-weight, and comfortable to hold in your hand. To me, it has a classy sophisticated look to it - not like something from a head shop or a woman's sex toy like most tube mods do. If anything it looks like a large cell phone or remote control. I got nearly 3 days between charges. It also serves as a passthru.
And yes, I charged my cell phone with it once just to see if it would. I prefer using the MVP in the car rather than my Mini Provari, because being flat-sided I can lay it on the passenger seat and it not roll out of my reach. Unlike my Mini, which I resorted to laying on my lap while driving. I don't wish to admit how many times I've forgotten its there and dropped it on the driveway getting out of the car.
I used the MVP as much as my Provari's, and anyone who knows me on ECF knows how I love my Provari's. It is fitting for a novice as well as an advanced user. It is equally comfortable to use at home as away. For $50 this is a steal. This mod deserves "Mod of the Year" nominations IMO.
* Added: To answer the question "Why buy a mod that uses a non-replaceable battery?", if one factors in that a novice doesn't have to buy multiple separate batteries AND a charger, the MVP is less expensive to purchase than a mod that uses replaceable batteries and will need multiple batteries and a charger. It can be used as a passthru which is a plus for many novices who may not have a backup to use.
Also consider the durability and expected life expectancy of most of the Chinese-made mods in this price category. How many Vamo's, VMaxes, Lava Tubes, Smoktech VV Grippers, etc are still in service after 1.5 years in use? If someone gets more than a year out of a Chinese made mod, they got their money's worth and more.
