I like it. I have a clear TPU case off ebay. Only problem I had with it was that the plastic stuck to the glass on the back so it made it look like there was water in it but not. I don't see that happening with the iphone 5 since it has a matte textured backing. I say get it if you like it.
Yep, my cases change color from clear to lint pretty quick. This is a cool feature. Still trying to decide what to replace my otter with, maybe will try this.
