My verdict

Final verdict: these nipple clamps are a mainstay of our sex life, and we are happy we bought them. My partner uses them on me the majority of our play sessions, and we both enjoy the hell out of them. We've used these for many hours since we got them a year or two ago and we'll be using them for many years to come. They look as good as when we took them out of the package, and they work just as well. The finish hasn't been scratched or marred, the tension is just as high. Nothing has changed and the clamps remain wonderful.

Pros

well designed
intense sensations
ease of use
secure

Cons

a bit bulky
slight tension imbalance between the two sides

Design

Lovely, practical, and intense

Sleek, comfortable, and easy to use. This sex toy is not only practical but also features an unobtrusive flat-black finish that fits any kinky occasion.

Quality

The last nipple clamps you'll ever need to buy

As soon as you drop it out of the envelope into your hand, you know it's high quality and well-designed.

Keep in mind that there's a slight variation in the tension depending on nipple sensitivity and clamp angle, but we actually kind of prefer it this way. My partner entertains herself by taking off the less intense side, making me howl by pinching my nipple as I anticipate more intensity as she releases the other clamp.

Experience

Mild to intense sensations and many surprising uses

Wearing the clamps for only a few minutes, results in relatively mild sensations, but tug on the chain and/or increase the time you wear it and you'll be howling in exquisite pain when released.

Surprisingly, these clamps have benefitted our play in several ways:

  • My partner is endlessly entertained by the clamps as she uses them for playful sadistic scenarios. She merely uses them to control and guide me, or to (gently) torture and tease me.

  • The clamps give me an erection boost, and makes my cock super hard.

  • They're a great tool for orgasm control, and I love that my partner is in control of my orgasms.

How this works:

The pressure/pain keeps me centered and focused on her pleasure. The clamps keep me from getting overly excited and accidentally cumming.

My partner often let's me continue to fuck her after she's climaxed and uses them to cut me off just before I also climax. She decides when I'm finished. This means I don't deplete my energy, so I'm more attentive and thirsty for her.

We've also discovered the clamps to be wonderfully useful towards my partner's pleasure: She uses the chain like the reins of a horse, keeping me perfectly in sync with her rhythm. This drives me insane feeling like her fuck beast, with her in complete control of me.

This takes a bit of practice, as in early attempts my partner would occasionally tug too hard and yank them off, causing me to roll off of her in excruciating pain as the clamps felt like they tore my nipples off. It takes a bit of control and positioning to get it right, but it's more than worth the effort and pain of learning the technique.

Performance

Exceeds expectations

This is the real deal for pain play training. It's the last pair of nipple clamps you'll ever need, and they'll last forever.

Materials and care

Easy to use, clean, and maintain

The rubberized teeth feel amazing when first released onto your nipples and the cool steel feels great in your hands when applying. If you're having so much fun that they get messy, you can just rinse them right off and they're ready to go.

Packaging

Simple and discreet packaging

They came in a small, discreet, and anonymous package. They slid easily out of a Ziplock envelope and appeared very simple.

Price

Perfect price point

Nipple clams are a small accessory and shouldn't be too expensive. It's very satisfying when you can get something that's affordable if it means stepping up your pleasure game. It seems like an appropriate price for this simple, well designed, and high quality product.

We won't likely spend much more for this type of accessory, but any less would make us skeptical of the quality.
