I somewhat got talked into this case by the person at the phone store, but I am glad I went with it. I like the holes on the back so you can see the bright color peeping through (I have a green 5c and a black case). It's nicely grippy and prevents the back of the phone from being scratched. It's slim and very easy to pop off and back on when you want to, but holds the phone firmly.
Given Apple's attention to detail it is somewhat odd that some of the lettering on the back of the phone shows through the holes...this bugged me at first but eventually I came to not mind it. Very design-minded people or fans of precision/clean lines might find it irritating, though.
Does what it needs to do...overpriced perhaps in the way phone accessories tend to be, but good Apple quality.
Okay, so to start, Apple said the circles in the case were to show off the beautiful colors of the phone itself (which I do agree is very beautiful) but the circles are kind of ugly. If I wanted to show off the amazing colors of the 5c, I wouldn't put a case on it. The only thing I don't like about the 5c is the fact that Apple didn't design a nice leather case like it did for the 5s. All in all, I think Apple made a beautiful phone
