this Game Boy (Jellylike rubber) cover is perfect. and is totally retro in the sense you feel a little nostalgic everytime you look at the back, the reason for the 4 stars is because where the docking conector is the thin rubber part of the cover can stretch, if it was more along the lines of a hard plastic so it was a little more firm and stretch resistent, it would be the Perfect case for all Retro heads, but for the price you still cant go wrong
Good quality, thick strong silicone case that fits securely around your iPhone 4 which protects it from minor impacts. It's not one of those that will slip off when putting in and taking out of your pocket either, it holds firmly to the phone and looks very neat and tidy.
Theres also great detail on the design itself which is the main reason why I purchased one.
