Here is a web sight that looks promising.
It is called Product Wiki.
I still think Amazon’s customer’s review is the best place to get product advice. I find that site the most helpful because you get a wide variety of people reviewing the product they themselves bought.
However, Product Wiki has some cool things I did not know about. I wonder if they are real. Like an exoskeleton that increases your strenght to 10x your actual strength. Or how about the faux bacon strip bandages. Cool idea. I like it. Overall I find this sight not to be very well organized and it lacks a broad range of products. Some of their items seem way overpriced. It is worth a browse.
Another wiki that has been highly recommended to Lisa and me has been Pregnancy Wiki. Lisa has learned a lot about her body from this site.
