Bought the CapsuleNEO in black about three months ago, its really a great case and awesome bang for the buck with 2 silicon pieces, 2 screen protectors, headphone and dock port inserts, the stand and the I and H frames. Mine had somewiggle...and call me what you'd like, it bothered the hell out of me. I also didn't like the raised logo on the back that made the case teeter left and right more than a naked iPhone when on a tabletop. Wiggle and teeter aside I will still recommend it to anyone interested in it.
However, I recently purchased a black Power Support Air Jacket and couldn't be happier. Easy to put on and take off, and does exactly what I wanted in a case from the start...keep the back from getting scratched. I also am astonished at how well the Anti-Glare screen protector is at keeping the screen free from fingerprints.
