She's just a hit because of the Gameboy that time influenced our lives.
But now to the shell. She fits perfectly around the iPhone 4S, only the silent switch it does not fit 100% strength. The switch is a little lower than the iPhone 4, so I find the term "for 4S" is not appropriate. You can operate the lever, only here it looks not so elegant.
The shell is down slightly soggy, since only a thin strip below the home button from left to right. This does not detract from the functionality but.
The on / off button and the volume up / down buttons are covered, but wonderful to use, that's like no shell. Only the headset you have to make sure that you clean the plug pushes a little stronger, so he is actually the iPhone there.
I am satisfied with the shell and would recommend this even further, if you can live with a few limitations.
