It is fact that you can get 6 MVP's for the projected price of the P3.
It is not rude to say it. It is called being factual. And yes, it is justification for a buying decision, when as was mentionned earlier, value for money is an important factor.
Everyone has different criteria for defining "value".
I have an MVP. Its a great value for the money. It performs nearly as well as my Provari, although it has noticeable voltage sag towards the end of its battery charge. The Provari has no such voltage sag; its last puff will be as good as the first.
I happen to prefer the tube form over a box format. That's a personal preference, and also factors into what I consider value. I use one of my Provari's every day; my MVP is collecting dust.
Although a well built and relatively durable device compared to most Chinese-made mods, the MVP is nowhere near as well built and durable as my Provari. If I should happen to drop my MVP on the sidewalk out of clumsiness, or should it fall into a mud puddle, I'm quite sure the MVP would be toast. With the Provari, I have no reason to fear that the Provari would be ruined for life. Even should it be broken, I know it can be fixed for a reasonable fee and be returned to me within a weeks time.
I'm not the type who likes to keep replacing tools when they break or dysfunction, no matter how inexpensive they are to replace. I prefer to buy quality which will last me what I consider to be a reasonable amount of time. An MVP, just because of its non-replaceable battery, is a disposable device that will need to be replaced within 2 years time. I expect my Provari to last me at least a decade. (Yes, I'm basically a simple vapor and a Provari in its current technology serves me well now and will continue to for the next 10 years.)
A company who stands behind its product for life is value to me. Once an MVP dies, its an expensive paperweight. That's a limited and short-term value despite its inexpensive price.
So, to sum up, to me a Provari offers better long term "value" than any other VV mod on the market. To others, what I most consider "value" may not be the same to them, and that's perfectly fine. Spend your money as you wish.
