Amongst the several available cases for the transformer this is one in the middle price range, which was the main reason to order it. The case fits very well, all openings like cameras, sd card, charger etc are free to reach. The material is OK, feels nice, let's see how it will look in one year. Also, doesn't add much weight.
I would like to see some material protecting the edges of the device, imagining it falling, it'll probably hit there first.
Overall, Very good piece for the price.
