The Endurance Clamp didn't lie.. it is increasingly harder to wear these destructive nipple clamps for a longer time than 5-10 minutes. I can personally wear them until I'm crying, which is about 30 minutes to an hour in these bad boys. They are purely satanic and so enjoyable for the wearer and the put-it-on-er. It is only for moderate to advanced pain users, beginners need not to buy this. You will regret buying this if this is your first pair of nipple clamps, don't even think about it.

These devils are actually made by the Spartacus company. I really enjoy all their products and plan to buy from them a lot more. They are excellent at workmanship and durability. Plus, I love the materials they use. I just trust their company so much.

These destructro-matics don't really make the parts of your body where you put the clamps destruct.. it just feels that way. I feel like my nipples are going to pull or fall off when I wear these. And in other places, oh baby. It is a pain experience. It hurts even more when you take them off because the blood is rushing back so quickly even if you take them off slowly. It is really some pain Olympics going on with these clamps.

Endurance Clamps are ONLY for moderate (on the higher side of pain) and advanced pain lovers. Do not even think about it, beginners.

Unfortunately for me.. or fortunately, I have an amazing Master that just wanted to put these clamps everywhere he could. He put them on my nipples are first. God damn, let me tell you. These clamps you really do need endurance to keep from taking them off yourself. I used ALL my will-power. Then he wanted to experiment with them on my clitoral area and right on my clitoris. He is obviously the devil but I do love him with all my heart. They are also not visible at all when you wear them under clothing.. FML. I learned that and Master learned that, and BOOM. I get to wear them outside of the house.. >.> The pain lover inside of me loves it, I swear.

These clamps are MADE for pain. If you don't like pain, don't get them. The little no-slip rubber covers even come off of them super easy (they were made like that) so you can get the full effect of these alligator clamps. Now, if you take off the rubber covers, ONLY FOR ADVANCED USERS THAT KNOW THEIR BODY. I stress this again, these little bitches hurt. It will break the skin easily and if you want that, power to you. I've only tried them without the rubber covers once so far and I was a huge cry baby. And that is coming from your favorite BDSM pain lover. You are warned.

The Endurance Clamps are actually made of metal and rubber. It is about 95% made of metal and only 5% made of rubber because of those little covers I showed you before, but those are removable if you feel the need to cry in pain while in a extreme play session, then it is all metal.

I really love the material of this product because it does have SOME weight to it and really hangs nicely.

A little about metal..
Metal is an element that readily forms ions (cations) and has metallic bonds. Metal is phthalate-free and has firm, smooth texture. It is usually shiny, with a high density, ductile and malleable, usually has a high melting point, and retains heat well. Metal also has a lovely safety rating of 9.

Metal also is Food-grade material / Latex free / Non-porous / Phthalates free in this product. If you do have an allergy to metal, I would recommend getting something else.

The touch of these clamps feels extremely smooth like metal should feel and cold. I really love feeling these beautiful clamps. I really am in love with them because they challenge me more than any clamp as done in the past. These are the ultimate clamps in my opinion, and for the price? You can't beat it.

The texture on the other hand is quite intense. While those little rubber covers try to make it less intense for you, it still hurts. You still need to use all your will power not to take them off immediately. When you take off those little rubber covers, you are going into some extreme pain level territory. You will either love it or hate it. I can't choose that for you, but I choose to work up to that if I can. I love my nipples and don't want them to break off into a million pieces of shed off of my body. I want to take it slow without the added texture. The texture it has now with the little rubber covers is enough pain for me right now. I can wear them for quite a long time before I go crazy and I'm begging to get them off, but most people don't have such a high pain tolerance and think sex is all about pleasure. BDSM play is certainly an interesting way of life, don't you think?

The design and shape of these clamps are divine. I really love how long the chain is and how it just hangs so nicely in between my nipples/breast area. I love the size of the actual clamp part because it isn't so big that it covers half my boob, it is perfect for my nipples. I do have small to medium nipples (check out my nipples on video if you need a comparison to yours) and they fit very snug.

These clamps are very easy to put on but the initial reaction I had to putting them on every single time is "oh my god, oh my god, oh my god, pain!" because it is that instant. You are instantly in pain. There is no "work your way up to it" in these nipple clamps. Instant pain. And it just gets worse and worse from there on out, in a really good way. Taking them off is really the worst part of clamps. The blood rushes back quickly to the nipple or the part where you put the clamps and it hurts like nothing you've ever felt. I always try to make the circulation go faster and twist/move my nipples around but it always doesn't work. You just gotta take it. Take it like a champ.

The Endurance clamps are very convenient to wear because you just clamp them on so easily. They can also be worn under your clothes and no one will have any idea, but you, and the person that made you put them on. Comfortable to wear? That depends on the person. For me.. it is comfortable to a point, but I like pain. You may not like as much pain as I like. I would be cautious when trying these clamps out for yourself. Experimentation is everything, babes.

These clamps are NOT adjustable in the fact that you can't adjust the pressure. You can adjust the pain and take off the little rubber covers. Again a reminder, if you remove the little rubber covers, ONLY FOR ADVANCED PAIN LOVERS.

The measurements are pretty amazing if you ask me :
The length of the entire product is about 16" long. Perfect length.
The length of the clamp area is only about 1/2" long. This is the ideal size for most nipples.
The width is only about 1/3" long which is great so they can clamp on correctly.

It is really easy to take care of these delicious nipple clamps. Metal is a great material to take care of.

Metal toys can be boiled or be bleached (10% solution), are dishwasher safe (top shelf), or can be washed with soap and water.

I personally just spray some of my favorite antibacterial toy cleaner on these before and after each use just to make sure that these keep being their amazing self. I don't ever want to ruin my toys. I try my absolute best to keep all my toys in near to perfect condition.

I store these nipple clamps in a little plastic baggie and put it in my toy box for easy access. It is small so it doesn't take up a great amount of room, which I love about them.

As far as I know, these didn't come in such an amazing package. I'm pretty sure these came in a form-fitting piece of cardboard that had a form fitting and see-though plastic packaging. You just need to rip it out of the packaging and use them. I wouldn't keep the cardboard because you can't re-use it easily unless you are a master at opening these kinds of products. T

There were no user instructions in this package which is fine because using nipple clamps is pretty self-explanatory.

The only thing I want to say more about safety, your nipples are quite sensitive. The first time you wear these, I wouldn't wear them for more than 5 minutes at first and see how it goes. You know your body more than I do so once you do that little test, try it longer if you feel comfortable, if not, work up to it. These clamps are really worth it.

My experience with these Endurance Clamps is quite an interesting story. I was taking to my Boyfriend/Master about getting some new clamps and I showed him these ones. He said they would suck and I wouldn't like them because they wouldn't be as intense as we play. So, I ordered them. He was so very wrong and he was happy he was wrong. This purchase was by accident honestly and we didn't know how intense it would really be. We are very happy about the product though, it really fits right into our pain play.

The first time I put them on.. well.. he put them on me, I wanted them off of me immediately. I didn't expect such an intense feeling so quickly. It is so pressurized that I thought my nipples were going to crush and never go back to their normal shape. (of course they went back to their normal shape, I don't want to scare you too much!). The chain felt so cold against my breast area and felt heavy to me. I think it was because the nipple clamps were so tight to begin with.

He was honestly so happy with his sexy smirk on, you know that sexy smirk when he knows he won something in bed? That smirk. I wore them for about 2-5 minutes and begged him to let me take them off. The took both the nipple clamps in his hand, gave it a nice pull, and un-clamped them at once on both nipples. I screamed a little. After taking them off.. I was fine again. I felt like I completed some kind of nipple clamp challenge. I wanted to try them again during our usual intense pain play that we love so much. We tried them again in bed and I wore them the whole time we did our usual BDSM play and intense sex play.

It hurt so good. I couldn't believe I was wearing these little devils and I could take it. Just barely though. In the back of my mind, I NEEDED to take them off.. but I prevailed.

Unfortunately for me, he noticed that the little rubber covers would come off so he took them off. He once again had that sexy smirk and I knew I was in trouble with these nipple clamps in such a good way. He looked at them closely and said, "This is going to hurt. I hope you love it as much as I love watching it". He put them on my nipples and I screamed. I told him that these were way to intense right now and since he loves me so much, he took them off because I genuinely had a concern. We took them off and looked at my nipples. They already had imprints from the alligator spikes in them and looked super red. I told him I wanted to try without the little rubber covers when I feel up to it and he agreed we should experiment with it more.

We also tried these nipple clamps on my clitoral area and clitoris. That was sure intense. He dragged me around with it like a leash. I loved every second of his power over me.

I honestly love these Endurance Clamps. In my head, I hate them. On my body, I love them. I love how they can make so much pain for me but so much pleasure too. I am just one of those people who like pain and domination from their Master.
