I just installed it, the thing is super TIGHT, no way it is slipping off.
I couldn't even take it off, dunno how the previous posters saying its easy. It could be that its brand new and hasn't been broken in yet, but the initial install is really tight.
Also installed Power Support screen protector and the Slider didn't interfere with it.
Good case though, handsome and light-weight.
EDIT: oh don't mean to have confusion but i had the click when i attached the bottom piece to the top, shrug YMMV
