It doesn't list everything but what it does list seems to be accurate (in relation to the products I own anyway)
At first I thought the high rated items were the good ones but I found out they use the votes to bring bad products to peoples attention,. Letting the community inform each other about possible issues with a purchase.
There is a page to request that products and issues are added, so as one of the other reviews said it will be a good resource with more community support. It is a little rough around the edges at the moment and needs more comments but its a service I hope survives. Five twinkly stars from me for a good idea.
