These work really well as nipple clamps. You need to make sure that you tighten them enough that they won't slip off, but not so much that you're really hurting yourself or your partner. Almost anyone can use these. You just need to listen to the person that you're putting these on. If they tell you that you need to loosen them up then you should. They can become very uncomfortable after a while.

You can use them on the vaginal lips, but it takes some work to get them on. They'll automatically be a little tight so you don't have to do much excess tightening.

You can wear these under clothing, but I wouldn't do so in public as even under clothing the bells do still make some noise. I recommend if you're going to wear them under clothing that you do so where people don't mind or that you do so only while you're still within the confines of your own home.

You can of course wear these while you're engaging in intercourse, but if you tug on them or you force the person to rub on the sheets it's entirely likely that they may come off.

The actual clamps are made of metal. They are cold to the touch, but that is avoided some by having rubber tips on the ends of the metal clamps. You can in fact take these tips off to add a little more bite to the clamp.

The clamps themselves are rather light and dainty, but don't worry they're sturdy.

The clamps have some give in them, but not an incredible amount. I don't suggest forcing them as there is a possibility that you could break the piece that slides up the clamp.

Overall the metal is sleek and simple.

I love the way that these clamps look. They're dainty and almost elegant. However, they do last very well.

Putting them on can be a little tricky as sometimes the piece you use to tighten the clamps doesn't want to slide very smoothly. It can lead to some accidental over tightness and some quick sharp pinches.

For the most part these are as comfortable to wear as clamps are supposed to be. I wouldn't say that they're actually comfortable though. Clamps aren't really supposed to be.

They're easily able to slip onto most nipples. The tightness is adjustable, but the overall fit of the clamps aren't extremely adjustable. Your nipples either fit easily in them or you have to put up with a little bit of struggle to get them on.

I love the look of these clamps. They're sleek. They're dainty. However, they can be a pain to put off although taking them off is almost always a breeze.

While it is convenient that you can take the rubber caps on the tips of the clamps off for a little more bite you can also lose those caps. Taking them off tends to make them looser and will lead to a higher likelihood of losing said caps.

They stay on well, but if you get extremely rigorous they will occasionally fall off. They're very comfortable for being clamps, but occasionally they can become a little too much to bear.

I store these in a drawer. I occasionally wash them and dry them off. I then set them out to make sure that they dry before I put them away, but they really don't need to be cleaned often.

While I love most Spartacus products I have to admit that these were not my favorite.
