Be warned, these pack quite a punch. These are not made for beginners and may need to be worked up to even by some advanced users. If you are into nipple torture, this is definitely for you!

These clamps are not for people with super sensitive or even mostly sensitive nipples unless they really enjoy pain! They're simple to use and easy to store away. With very strong clamps, they provide a lot of pain really quickly. Great for masochists.

This is a simple toy that performs its purpose perfectly. It clamps down on nipples hard and creates a lovely sensation. Not for a beginner, but great for a BDSM enthusiast, especially masochists, or a great toy for a sadist to buy for their partners.

Overall I think everybody who enjoys some bondage every now and then should have a pair of these clamps. However, they do pinch pretty hard and not everybody would probably enjoy them. With their versatility they are great for many kinds of play.

If you can withstand a pretty heavy bite and are looking to step up to the next level in your nipple play, then look no further: these clamps are for you.

I was disappointed when I got these. Not in the product, it is wonderful, but in my lack of ability to tolerate the pain they cause. They are beautiful and look wonderful on, but do not take them lightly, they hurt.

These clamps are not for the faint of heart. They aren't adjustable, so there's only one setting: Ouch. But if that's what you're looking for, then grab these puppies up!

If you are looking for some serious nipple clamps for pretty heavy duty NT/ You will love these clamps. I rated these as being very quiet, but the screeching you may get from your sub is anything but quiet.

These nipple clamps are great for someone who more into masochism than the average person. They have a nice look to them and feel good against the skin. They can be used solo or with a partner for increased fun. They're also quite affordable!

Butterfly clamps aren't for the faint of heart. They are a serious BDSM device. We happen to enjoy pain play and have worked our way up to the significant levels butterfly clamps require. If you're ready to step up from clothespins to butterfly clamps, get this set from Spartacus. They will last a long time and perform just as they should.

Personally, I love these clamps because they do exactly what they're supposed to do: pinch hard in one spot until released. If you like pain, especially on your nipples, or just like intense nipple play then you'll love these, too. The clamps are sturdy and well made, though they have a few little spots to watch out for. However, if you're playing safe these things shouldn't be an issue.

How much can your nipples handle? Want to experience some of the most intense nipple stimulation out there? Are you a kinkster who enjoys pushing your boundaries? Clover clamps are one of the best things you can get for your BDSM toolbox. These are well-made, "comfortable", highly intense, and never manage to disappoint me. I really don't think my life would be complete without them.

A fantastic toy for the advanced player looking to inflict pain. We've used this style of clamp for many different styles of play and it just never gets old. These are your last step before having to start shopping for clamps at the hardware store.

Far from their benign sounding name -- Butterfly -- these high intensity clamps really get the job done in terms of delivering sweet, delicious pain.

When you want the best nipple clamps with a pretty name and nice to look at and hurt like hell: the Butterfly nipple clamps are your obvious choice!

The intense sensation is unrivaled by any other clamps I've come across. They are durable, attractive, and sturdy. Not for beginners, this is a hardcore BDSM toy and not for the faint of heart.

I would like to say that I've had two sets of these clamps. With my first set, one of the little rubber discs came out. I was still impressed enough with the product that I purchased another set. I've been very happy with my replacement set and have used them more times than I can count. I would definitely recommend these clamps.

Butterfly clamps are evil little clamps with a deceptively cute name. They were originally a sewing accessory that was corrupted to kinky use, and I, for one, am glad that they aren't stuck in a sewing basket anymore!

Basic nipple play not doing it for you? Like your tweezer style nipple clamps but aren't getting the bite that you deeply desire? You might want to intensify your experience with the butterfly nipple clamps. They are an acquired taste, but don't give up too quickly.

The Butterfly Clamps aren't for the new of clamps, but if you are looking for something that will hold strong and provide a bit of "bite", these fit the bill exactly. They are well-made and hold strong wherever you clamp them.

These butterflies will make you flutter about the bedroom or play space. If you enjoy nipple play or want to experience something a bit harder on those sensitive bits, the butterfly clamps are a great way to achieve your desires. Unyielding and strong, they are sure to leave you aching for more, or just aching.

These clamps are high quality and great for people who are familiar with nipple clamps/pain play. However, if you are just starting out I would highly recommend steering clear of these as the sensation is a higher intensity than will probably be enjoyed.

Into serious sensation play? Love pain? Love intensity? Then the Butterly Clamps are a definite serious step up from all the other nipple clamps available. Be brave though, very brave!

Great for role playing! Its a heavy duty piece of equipment that is best suited for the experienced player but adventurous newer players will grow to love it as well! WE love the look and fell of the clamps. The only thing that would make it better would be if we could back off the pressure just a hair. Definitely a great addition to your dungeon.

Not for beginners. Make sure you know how to use clamps safely and go slow with these. However, for people who like it rough and know how to use clamps, there are very well made, very effective, and beautiful. Smooth metal with textured ridges on the inside. Not adjustable.

These clamps are very strong, very well made and for serious sensation play. They will hold up for extended use and are a worthwhile investment.

These are some MEAN clamps! And I say mean in the best way possible, but not everyone would agree with that. These latch on and do not let go, and are designed to tighten when the chain is tugged on. They will stay on even the smallest nipples through tugging, twisting, and pulling. But if you're a beginner or cannot tolerate intense nipple pain, these are NOT the clamps for you! Definitely not for the faint of heart, but perfect for those looking for nipple pain and torture!

The Butterfly nipple clamps are for advanced users only. I can’t stress that enough. They are hardcore to the max and painful to the bone. If you love nipple torture, and I mean really intense, spine-tingling, ouch-inducing torture, then this is definitely what you might be looking for. Although they aren't my style, they're worth the quality, the functionality, and the price.
