The first review was from a fiverr gig. I have seen this persons gig as well as reviews for several products. all pretty much the same. Him sitting in a studio with his headset around his neck telling how great the product is.
Two of the reviews are from guys, obviously in there bedroom. The first one did not even make his bed and looks like a slob. Not that he is a slob or that he is not successful, he just does not project a professional image. The second one was a kid, well he looked like a kid, early twenties at the most. Again, in a bedroom that looked like a teenagers bedroom in his mom and dads house, posters and a little un kept.
People should not judge a book by its cover, but we often buy a book because of its cover. The cover is the image. and the image I got from the video reviews was not that good.
In the IM/MMO niche it is tough enough to get a half way decent review for your product. I think you might want to think twice about video reviews, or at least view and be a bit more choosey about the ones you post with your product.
Just my opinion
