I have this, and I'm pretty happy with it. It is only meant to be standing up in landscape mode with the speakers on the bottom, almost straight up. Don't expect to be able to have it slightly angled off a desk or your lap or anything. I don't have a touchstone, so I can't comment on compatibility. It has a small velcro strap that connects behind the TP to the inside of the case, and it feels very secure. IMO, this is well worth the $13.00.
