The allen key hole in the back is slightly rounded on one so you just have to be a bit careful. With a good allen key and not rushing it tightens up perfectly though and can be taken off fine too. Springs are good and bearings spin well.
I've ran them brakeless for a fair while and have never unclipped
Grey ones been by @timbre.
Yeah same as current cleats.
