I bought this case to tide me over until the case market is a bit more fleshed out, and I'm pretty pleased with it so far.
A few details that I really like: that the lip is not only thin, but flat on the face and beveled on the inside, the bottom of the case with the perf'd speaker holes and dock and jack cutouts which looks much better than the wide open bottoms of most cases and the general slimness of the case.
Three things I didn't like: the Anker logo on the bumper, the glossiness of the bumper and that the bumper wasn't attached to the TPU. I fixed the first two in about 2 minutes by taking 1000+ grit sandpaper and brushing the bumper (after removing it) so my bumper is now matte/satin, which I really like, and the logo is gone. I fixed the third one by just supergluing the bumper to the TPU.
