Good quality and they function as you would think real handcuff would!

I am satisfied with the item

I did buy this as a toy for the bedroom, but it really is heavy duty. I guess I could really use it for my future career. It's sturdy and well made, but definitely be careful when using it as a toy.

Exactly what I was looking for

The video shows me dropping and smacking them to try and rely weight, size, material and heft.

if 50% is average, my wrists are 45% for someone 6ft, 170lbs
These probably won't work on a 'very large individual'. At least, not comfortably.
But if my experience of watching cops for 30 years, everyone says they are tight and no one wears these for enjoyment.
Well .....Okay, you know what I mean...

I like them so far.

I bought these for general purpose. Something I'll probably never need, or if I do, it will be for costume purpose.
However, they seem legit. I can't break them and I did try. 6ft, 170lb. They feel like they could take a lot more than I can dish out.

They work without flaw and I have no complaints. The price is very reasonable.
They will be going in my emergency kit for who knows what. Cray mofos on pcp perhaps.

One key will go on my keyring.. Not paranoid. But ya never know when you might want to escape someone who put these on you. Frat party, scorned lover, or abusive cop. Why not?

Oh, and if you're buying these for kink. Go with something a bit more gentle. These are not forgiving and not a toy.
Unless you like that. Then you do you.
