It can happen... if you have a presence somewhere. For a while I was getting asked for reviews simply because I post here but a) gosh that means video or at least pictures and whatnot, and well, I enjoy vaping on its own merits, it's more fun for me.
Also, I genuinely believe there are many others FAR more capable of reviewing than me. They really are.
I would try some reviews and post them for some honest feedback, and it may be brutal, because mine is a) you seem a bit naiive about the review process like someone is gonna "send you something to your door" you sound as if you may not have WATCHED many youtube reviews and what goes into them (you should do that, BTW) and you need a better command of the English language.
To be fair, I have seen a few reviews that make me go "Man, I should TOTALLY review!" but they are few and far between and it's because the manufacturers are Not Impressed.
So, my advice is get a little vaping under your belt before you expect the big manufacturers to send you expensive products to your door. It comes off as a bit... entitled to me. No offense.
