Mickey, I think there's a couple reasons. None of them good.
1. The bar has been set low. A lot of companies you are lucky to get a response from let alone a video.
2. I know from regular bass fishing I just buy baits that look like they can fill a need and hope they work FOR ME. Everyone fishes a little different, what works for one may not work for another, thus "reviews" can be worthless and unfortunately in some cases misleading.
