I have had this case on my iPhone 4s for, I think, over a year now. I have dropped my phone several times since then. It hasnt cracked or broken at all. I love it and someone actually asked if I had a gameboy in my pocket one time! It fits the phone well and protects it well too. I have bought a few colors and for some reason the yellow fits best. It is cute and reminds me that I have a Gameboy to play too. :)
Everyone will be very interested with your case. Its a nice bright yellow and fun to look at. Only issues is it leaves a yellow stain on your pictures. I mainly see the yellow when I use the flash. I just pull the top of the case down when I need to take pics or don't use this case when I know I will be taking a lot of pictures. Not 100% durable either the rubber helps from scratches but don't expect top of the line coverage.
