Chacun à son goût.   If it works for you, great. I would say be selective. I feel quite differently.

Long time no see! Glad you are still in touch with your Inner Freak.
But, no, I have no handcuff fetish. A very hot Dominicana wanted to cuff me a few years ago and I told her no fucking way am I gonna be chained to a bed in an airport hotel. I still had a great time with her.

I have never had an interest in being cuffed or restrained. But I have used the velcro cuffs, ropes and blindfolds on 3 ladies that were willing.  I earned their trust after seeing each one multiple times and asking in advance.
The result was they ALL loved it, all had huge orgasms, and all of them wanted me to do it again.  One has retired, one is basically utr - regulars only, and one is still very active.
I always went home very satisfied. Give it a try.

My bondage kink is topping, but no I won't use "real" (police-type) handcuffs on a partner in sex play.  Reason: they are designed to hurt if struggled against, and will do real physical damage if pulled hard or overtightened (even by accident).  I do know about double-locking.

I want my playmate sufficiently helpless (I'm an engineer, so no looseys!) but not hurting or in actual danger of injury.  It's the same reason that I don't use bondage collars even though porn with them is hot.

Just my personal assessment of the plusses and minuses of this type of handcuff and my personal risk tolerances.  You do you!

I bought a 45ft roll of 1.5" wide velcro  one-wrap for $16 on Amazon.    Cut like a two foot section of that and warp it around someone's wrists.  They aren't getting out, at least not very quickly.  And it isn't cutting or uncomfortable. You can also cut a section and wrap it around their ankles.   My favorite trick is to cut a length and use it as a pants belt.  Then in an instant I can rip it off, and bind the poor victim in a couple seconds (we arrange this all in advance, of course.)
