Overall, I thought the clamps were very nice. As it states, they are adjustable, so it can hurt a lot, or they can merely hold their place on the nipples. I especially liked the look of the silver chain against her skin, which looked even better when the weight was added to the chain. All that being said, I am the only one who liked the toy; my wife thought she might like this type of toy, but actually hated it.

Even adjusted to the max (least painful), where it barely stayed on (and without the weight), she found them painful and not enjoyable. This should not have surprised me since she has very sensitive nipples, even to light pinching. So if I had really put any thought into the purchase, I should not have bought this toy. But hey, you gotta try.

You could easily share this toy without any serious cleaning provided you don't break the skin with the clamps, so you don't get any bodily fluids on it when used on your nipples. However, if used on your genitals such as your pussy lips, a light cleaning might be required. Since it is small and easily hidden, I would say it is travel friendly, but the TSA agent at the X-ray machine might wink at you when these get X-rayed.

One thing I noticed that I was not a fan of is on the clamps themselves; they have an "alligator mouth" design, but the pointy teeth are dipped in latex to avoid serious pain/cutting. This is all well and good as long as the little bit of rubber stays on the teeth, but ours did not. Thankfully, this happened during storage, not during use, as I could see that being a real issue. This problem could be easily fixed on your own using tape, or anything really, to cover the "teeth," but I know I do not like having to "fix" toys I paid money for.

Like I said, my wife hated this toy. So, I would say our experience was a fail, though not through any fault of the toy, as it did exactly what it is designed for. Even barely tightened, where the weight of the chain alone would almost pull it off, it hurt her so we couldn't get too much feedback on the toy itself due to lack of use.
