The stock is fine but the locks are awful. Will never be able to let a spectator lock it. Took a while to get the locks to work. Will have to get new ones.

I've always loved this trick. The bar is great, chains are a bit loose but with pliers I got them "tight" enough to not seem like they can be slipped. The real issue is the locks. They're hard to use, and seem like they must be gimmicks to audience members. But I just use my own instead!

There isn't really much room for things to go wrong with things like these, but still, I figured I should make a quick comment.

These are great. They do exactly what they are supposed to do, they work smoothly, they feel sturdy. The locks has a slightly gimmicked look to them, which some performers might not like, and they don't look as extreme as some of the heavier versions of this. When that is said:

These fit in my jacket pocket. I bring these out and perform on the street, on the spot. The might not be as heavy as other models, but they are highly portable, look impossible, and work perfectly.

I've used the chain escape for my wrists and loved how easy it is to escape from and return to.
So now I've purchased a second set for my ankles.
(I'll stand in a cardboard box for this set.)

The chains were not very convincing
