For the most part, it's pretty good. I dislike that it uses flash because the side scrollbar tends to get lost pretty easily. It always takes me a moment to figure out how to scroll horizontally which is frustrating.
I'll think about it. There is some ideas that I think could surface on the product comparison side. Check options on the search for product comparisons. Similar product- check the option to find similar product in different material, more expensive material, less expensive material. One that is more highly rated. One that is reviewed more. (Not sure- pretty tired right now)
This post is getting buried, but I'll admit that I love having it. An incredible feature.
