These clamps are meant for the nipples; however, I don't see why they couldn't be used on the clit if you'd prefer to try them that way - which I have not done. They are adjustable and the clamps work well. They were tight enough that for safety reasons, we had to loosen mine up a little after about ten to fifteen minutes to leave them on as long as we wanted to, which was close to an hour.

They are easy to adjust and have little soft/smooth ends covering the metal, so they're not abrasive. I think they would be good for beginners, however since there are very few clamps that vibrate on the market currently, I'd say advanced users could use them too. I'm still looking for a better set, but these are better than the other set I currently own. These clamps are unfortunately not waterproof.

The clamps are made of metal and plastic, with cords leading to a plastic controller. They are seamless, and adjust easily. They use 3 AAA batteries. They have soft tips cover the metal, which is nice, however the tips come off too easily. They are not waterproof, and honestly, are pretty loud. I tried leaving mine under a thin cotton bra, which did not change the way they felt, but did make them quieter.

The cord seems slightly too long in my opinion, but works well enough. The clamps stay on well, which is a plus over others I've tried. They are easily adjusted with a little screw-like item, which is common in most alligator-style clamps. Like with others of this style, the screws don't always like to push against the metal in the right place, so the one clamp needed to be played with a little more than the other one to adjust it. They should fit essentially everyone.

There are seven functions, which do travel into the clamps. I wish you could feel them more strongly in the clamps, however you can still feel them. The plastic and metal make the clamps louder and don't conduct the vibrations as well as I'd like. The controller is easy to use, though I wish instead of simply picturing 7 solid lines, the lines would light up to tell you which number setting you are using. There is a power light that blinks with different settings, however it displays the type of vibrations being used, not which number you are using. These clamps are stimulating, though not as stimulating as I'd prefer. I think the bullets could also be a little smaller, and the clamps a little quieter. I think they'd be better as a PU coated plastic bullet with clamp ends - much smaller, stronger vibrations, and quieter. I find these clamps comfortable to wear, however I don't mind the clamping sensation, which not everyone is into. Overall, I like these clamps and will be keeping them.

Cleaning is simple; just wipe them down, or carefully use soap and water, or toy cleaner.

They come in a clear plastic bag, with no other packaging and no instructions.
