I love this watch case. I got the polycarbonate version from Best Buy. The only problem I've had with it is activating Siri accidentally due to the crown cover sticking out pretty far. And no, it's not hard to put on or take off.
I love this strap or case whatever you wanna name, it's ****ing cool and original looking. My aluminum version picked up tiny dings here and there but that's to be expected since aluminum itself is soft. Just wish I wouldn't have to take it off to charge it every 24 hours!
