I like simple design with transparent / milky back.
In this case, I noticed something that can slip easily, then the hole for the microphone is hidden below closely. So put the best mobile phones from top to bottom in the shell.
Should be noted, perhaps, that in the white S3 the back of the phone now and then clings to the side of the clear silicone cases and then looks as if some water in the shell.
Of definitely apart a model that I can recommend to anyone.
This version is the way shipped directly from Amazon (the last I received via Amazon Marketplace). I think this option is definitely better because it enables eg Overnight Express.
