These little guys are definitely a great buy. They are quite lightweight, but very durable and well made. I can't see them breaking anytime soon. The clamps are small metal tweezers, about an inch long that are capped with black rubber. They have a small sliding ring on them to adjust how much they tighten. The tweezers are then connected by a twelve inch metal chain. The chain is heavy duty, but light weight. It gives a bit of a tug when dangling, but doesn't yank. For those of us (like me) who are number-challenged, twelve inches is enough to comfortably dangle in a smooth arch between nipples and long enough to just barely be held between the teeth, if one tilts their head down or lies on their back. The sliding rings to adjust squeeze are a bit sticky. They don't glide smoothly, forcing one to place the tweezers over the nipple and hold the tweezers closed at the desired level of intensity, and then slide the ring into place with the other hand. They are not the easiest to put on. In face, both my partner and I (with very different size breasts and nipples) both had equally as much trouble getting them to stay. Unless they are on their tightest setting or clamping the skin just behind the nipple, they tend to slide off with just a tug. Which of course is fun too, but to each their own.

The clamps clamp to what I would call a fairly minor extent. Left on for about 20-30 minutes in the tightest setting they did start to sting, but they were never so intense that I HAD to take them off and they were more stimulating than painful. For me, since I'm not a masochist (as much) and have a low pain tolerance and extremely sensitive nipples, this was perfect, however to someone with a high pain tolerance and not so sensitive nipples, they may feel like nothing at all. My partner (who also tried them and has a slightly higher pain tolerance and is slightly more masochistic than I am) called their bite "mild to medium" and noted that you have to put them on a bit tighter than you actually want them to be, as they loosen a bit with the weight of the chain and over time. So, noting this, I would say that these are a beginner's toy. They seem to be ideal for someone who is interested in nipple play but hasn't ever tried them and doesn't want to go full out. Their price also helps for this. They're a great deal for the price they are. However, if you are an experienced sadist/masochist/player and know what you want, these might not be for you. They're awkward to use and more stimulating than they are pain-inducing.

My partner and I did try some clitoral clamping. With patience, a reasonably big clit, a lot of skill, and preferably very little lubricants (natural or otherwise), it can be done, but it's pretty difficult we discovered. The clamps simply wouldn't grip onto a surface that slippery for long, however, we did have some fun with putting it on, pulling it off, and putting it back on again. So if you're into that, you might want to try it.

The packaging for this toy was discreet, small, not difficult to get open, and decently gender-neutral which I appreciated. Many companies advertise nipple clamps with pinks, purples, and reds, which is upsetting to those of us who have nipples (and breasts) who aren't femininely-identified, and I'm equally as sure it pisses off those nice masochistic bio-boys in the world who go "hey, hey, I have nipples too you know!" So, thank you PHS International for making smartly sensual packaging choices that choose blacks and reds and metallic-like modern designs more than females (though there is a female on the package, she's not wearing the product, so she could just as easily be your dominant or whatnot). I tip my hat to you, PHS International!
