I also just got my Caze Thinedge.
Great feel, super, super slim. The lip doesn't extend over the front like in the case of the 4/4S version. The benefit here is there is no screen protector lifting. The downside is that the case is a little loose on the sides. There is a bit of give due to it not wrapping around the front of the phone.
Mine also came with a slate colored clip, as well as a red one. I am using the slate one and it looks very nice.
Overall, great case. One I will be using for quite some time. I wish it was a little tighter, that is the only downside. I have skins on the back and sides (as well as screen protector) and the fit is not super tight. You have to work it a bit on the corners to get it to wrap around close enough to install the clip, but that's no biggie.
