It is more expensive but it's worth every Euro-cent. After my iPhone 5 fell on the floor (but wasn't damaged except a small bump on the side) I started looking for a good protection case. A friend who had this case (PixelSkin HD) showed it to me and I was very impressed. I ordered it without second doubt, and I am not regretting it.
It fits perfectly, the quality and material are of high-standards and I feel my phone more "safe" from accidental drops. I strongly suggest this case for anyone serious enough to protect their investment. After all, expensive gear (phones, gadgets etc.) deserve good quality protection, and Speck offers that from the first day of use.
All useful buttons and plugs are available (volume, mute, power, camera, flash, headphones, charger/USB cable) and thankfully, the SIM slot is covered. The microphone and speaker (bottom) have proper openings and are not blocked in any way.
I personally am very happy, even the color is very nice on my white iPhone 5. First-grade product.
