I agree with the other reviews, the collar is super comfy and the clamps are sexy but finicky. Definitely not ideal if you're moving around a lot. My partner likes nipple play so I put it on him during oral since he's (mostly) still then.
The clamps seem kind of like an after-thought on this collar, and I really wish there was more length to play with! The collar itself it very nice, but forget using a leash or tugging on it at all without the clamps coming off.
If you’re using the clamps - as the collar isn’t much fun with the clamps dangling, in my experience - you aren’t easily able to lead someone around with a leash, and their head/neck movements must be a bit calculated, as to not dislodge the clamps. Sometimes, that’s the whole objective; sometimes, you just want it to be a dual toy that is one-size-fits-all; unfortunately, this collar with clamps is not that.
and so are these tweezer clamps, but like most clamps in general, it's easy to lose the little grip on the tip. Once that's lost, it's hard to replace, then it renders the nipple tweezers unusable. I just took the chains off the collar with a pair of pliers and wear it as such. I like the quality of the collar itself, but too bad about those clamps!
