Good Review

This is one of the worst books I've ever looked at and read. It's just a waste of time. Save yourself 4 days with your friend (who isn't reading as well), read something, anything! You will actually learn more watching paint dry. In all seriousness.
Bad review

I was excited to get this case, but the case got stuck while my husband and son were putting it on for him. There is a lot of "give" when you put your iPhone in, so there is no way his phone can come out without damaging it. He's going to have to go out an buy one from somewhere else. 
 Rating: 2.0 
 Don't know what happened, but mine came cracked at the bottom corner just below speaker grill. It looked like someone dropped it.
