These clamps are a great addition for a beginner into the world of clamps, and BDSM. They probably would not please someone looking for a more fierce bite, as they are pretty soft core, even when fully adjusted to the tightest setting. They gave plenty of bite for me to enjoy, but I have really sensitive nips, and could still handle them fully tightened. I'll be the first to say I am a wimp when it comes to painful nipple play. I would recommend using a bit of super or hot glue to secure the rubber tips in place, mine kept coming off, but that was easily remedied. I did not have any further issues. These have been a great help for us, in training my nipples, I guess you could say. Before I started using nipple clamps, I was so sensitive I almost could not handle having them touched. Now, after using these, I can actually handle being stimulated with out jerking away. They have really helped improve our sex life.

The feathers are real, and feel amazing. They are very sensual, when lightly brushed against your skin. I used these many times just as a mini feather tickler and not as nipple clamps. A word to the wise though, if you have furry feline friends in the house, keep these pretty gems up and away from tempting them. I unfortunately, left these on the bed one day, and came back to a destroyed mess of feathers, and a happy little kitty.

I feel like the feathers could have a bit smaller. They are beautiful, but by the time you add the length of the feathers to the length of the clamps they were hanging down on my belly. This was distracting, as it tickled me, and caused me to bust out laughing. I believe this would work for people with almost any nipple type, I have pretty small nipples, that often have to be coaxed to peak, and had no trouble keeping these on myself. They never slipped off, unless they were just too loose, in which case I adjusted them.
