I'm going to be blunt. This is a pretty awful product. Don't go there.

Here's why: nipple clamps are meant to clamp the nipple. It's kind of in the name. These? They don't clamp. They hang desperately onto your nipple for a few short minutes, and then fall off and land pathetically on the floor by your feet. They didn't need any encouragement to do that, bar a bit of Newton's force. They just decided they couldn't be bothered anymore and gave up.

We tried, we really did. We picked them up and reattached them, and five minutes later, they'd decided they wanted another rest. They have no stamina.

The business end of the clamps are tiny; if you have nipples bigger than the tip of your little finger then you're probably out of luck for getting them on comfortably. They're fiddly and awkward to put on as well: typically, screw clamps will screw tight, whereas you have to unscrew these to tighten them.

For the brief moments the clamps attached themselves to my nipples, they did feel reasonably tight; they do unfortunately rapidly loosen themselves from the nipple and fall, though. I suppose if you intend to use them whilst lying down, they might prove more useful, but I personally find nipple clamps a bit more fun if you can tug on them for extra sensation in addition to the tightness - whereas I'm pretty sure these things would come away in the hands of the top, with very little resistance.

Further, the pliers on the ends of the chains are completely ridiculous: as soon as gravity has its way with them, they hang open and just look a bit daft. If the clamps were useful for their main purpose, I suppose I could spend five minutes with a hot glue gun and fasten them closed, but honestly, these things are being put in a drawer, probably never to be looked at again.
