I bought this thing for my tf prime.
It is an essential accessory, when you move around and put the tablet in potentially scratchy environments.
It also works great as a stand.
The manufacturing quality, however, is appaling. Mine began to peel off, and I had to glue it all back together with a textile glue. You would think that for this kind of price, they would mind the quality, but sadly not so.
Still, I find this a lot more useful than the TranSleeve Dual, which I also got, and which I hardly ever use.
