Many women enjoy nipple stimulation, and many like the effect of having erect nipples; some are into S&M, but regardless of what your fantasies are, these adjustable and secure vibrating clamps can be as gentle or tight as you want them to be.
Don't like the idea of having your hands tied up with a controller? Have no fear; a simple attached belt clip is the solution.
Now back to the vibrating functions (that's the part you're interested in most, isn't it?) There are eight speed settings you can control with plus minus buttons, and they can get extremely powerful, if somewhat loud, and the one-touch button with the arrows cycles between three vibrating and pulsating functions.
So on the whole, these clamps don't mess around; they're top-notch, but safe, so beginners can also experiment with nipple stimulation as well.
