I can't see how anyone can complain about this product for less than $6 & shipping included. Does it feel kind of cheap? Yes. Is it the sexiest case in the world? No. What this product does provide, however, are significantly improved ergonomics - especially when being forced to use the back touch pad as many PS Vita developers awkwardly incorporate into their games or when using it as a PS4 controller. The case snaps easily into place and even after several hours of extended playtime it didn't creak, shift, or impair controller function in any way.
For the price, you can't go wrong. But what if I hate it? It was only $6.
