This case/bumper feels very rigid and grippy despite the shiny borders that clamps down the sides of the phones. As you can see, I bought the yellow version to differentiate my phone a bit in spite of the boring black phone. The buttons feel pretty solid and aren't mushy as some might be worried. The case seems to offer decent protection too, and should aid against minor bumps or drops. My only complaint was that it does make the phone a bit wider and taller than other cases I have. I have an old blue TPU case that I bought a long time ago, and it is ever so slightly taller and wider in comparison. Most shouldn't notice the difference though, I just have an eye for those niggling details.
Overall, I'd give the case a 9/10. I think it's superbly solid for the price and I love the colors of the black and yellow that it provides my phone.
Also, sorry for the bad photos. I didn't realize how bad my old digital camera had gotten.
