I like that it still fits in the TV mode dock. I don't like sharp corners. If they were rounded or had finger indentations, it would be more comfortable. Judging by the photo below, rubber. No, that is not so! It's hard plastic, so no, you can't round the corners yourself. It's just cumbersome to keep the Switch in this case. I've been trying for 4 days and just can't get used to it. On the sides they pierce the inner part of the hands, and from below the corners are rubbed with the fingertips. As I said above, if the corners were rounded I might consider redoing the case.
