The swivel clasps are the best part, honestly. We used them solo as wrist cuffs one night before even attaching the bar, and they held up great. The bar itself extends far enough that my partner actually had to stretch, which was exactly the point.

I was worried the bar would feel flimsy, but the metal core holds up way better than I expected. The swivel clasps let me clip the cuffs straight to the bar or take them off for separate use, which is nice. Ten minutes in and my partner was begging, so it's doing its job.

The bar extends way wider than I expected, which made it way more versatile than our old fixed-length one. Clasps held tight through everything and the cuffs didn't dig in at all.
