I have this cover for my friend worried because you never had one, and I also use your phone to play. For me, the Sony Xperia SP has always been slippery and was thus not very comfortable to hold. But this has changed with the envelope and the cell phone takes better, even with sweaty hands is still everything under control. The fit is very good, the phone works by though but it's something bulky already been. If the envelope on the phone is, you can see the white very good, is not so attenuated, clear as it should be. Smell does the Gümmihülle, even after long use. If you count the price of it, then I can forgive only an absolute buy recommendation.
I have my rating of 5 is set to 3 stars down because the provider has sent me an email after purchase and promised to a customer review (detail) another shell in a color of my choice to send for free. After several requests I have never received an answer. Nevertheless, the product is very good.
