Otterbox Samsung Galaxy S II Commuter Series Case Review
 

The Commuter Series Case from Otterbox for the Samsung Galaxy S II phone offers good protection, without adding a lot of additional weight or making it too bulky. The product is composed from two layers, one silicone and the other one a high quality polycarbonate. Otterbox also includes inside the package a protective screen, along with the usual soft wipe and squeegee.

Looking into Otterbox for iPhone as the current cheapo plastic one (with fancy leather) is almost dead/broken after less than 6 months :(
