The Cygnett Urban Shield works in the Samsung official dock, but not a 3rd party one I have. Still, this is better than non-carbon fiber cases, that fit in no docks at all.
The Cygnett Urban Shield's primary purpose-- to protect the phone, it does. I've dropped it a couple times, and no issues.
Still, I'm on the lookout for a slimmer case, that allows me to use docks.
The Cygnett Urban Shield snaps together in 2 pieces, that I'm not won over on. My previous case used flexible plastic, which I suspect is more reliable, in the short term anyway.
