Looked at a few products I'm familiar with, and it appears you're doing pretty damn well at summarizing the high and low points for them. Nice work, bookmarked. It's pretty rare to find an affiliate model type site that actually adds value.

Edit: You'll want to watch out for people scraping your work and hawking it as their own though. I did something kinda similar by taking poor OEM images and cleaning them up, adding some rotation/depth, improving product descriptions, specifications by hand, etc. Scraped and copied by competitors pretty soon thereafter. Then a whack-a-mole DMCA game of getting rid of the ones that didn't bother to even change the copy.
