These are fantastic for if you won't be moving around a lot and they transmit quite a bit of power for being as small and thin as they are. The vibrations are very strong and tingle like a gem. If you have a vibrator or someone wearing a cock ring stimulating down below while controlling these to stimulate your nipples, your mind will go bonkers.

I think it is best for those with smaller areolas as they can then cover most of your nipple and make you feel the sensations all over. As usual I encourage everyone try things for themselves if they are interested.
