Didn't see a topic devoted for those, so here it goes. Do you use them or not and why's that, plus other thoughts.
I'm myself looking forward to getting a new pair of real police cuffs, and was wondering whenever anyone has any recommendations - I already know that cheaps brands (e.g. Alcyon, no-name 15€ cuffs) are to be avoided.. but anything else one should know? (e.g best places to buy, tips and tricks, etc)..
EDIT: Thanks for suggestions. Good ones

Heh. As of double lock, I vote for the push-button double lock - common Hiatts/S&W do not seem to have that for a strange reason, which is kinda strange - it is much faster to double lock the cuffs with a pushbutton, and it gives some creative freedom within self-bondage..
