So I've got two skates in with these and feel as though that's enough to give my verdict.
If you like your skates extremely tight, I don't feel as though these will be for you. I've got them set up on my Graf Peakspeed Pro Gs about as tightly as they'll go and while they're secure, they're not as tight as I'm accustomed to. For me, I'm finding this to actually make my ankles and feet feel better after an hour on the ice.
They're extremely quick to put on and remove and the level of tightness you get is consistent and doesn't change from the start of a game to the end. I did find that one of the screws loosened each time out, however I've since added blue loctite and don't foresee that to be a continuing issue.
I don't think these are better than laces, and I don't find them to be worse either, they're just different.
