The My Miracle Massager offers a long electrical cord. The low setting is rather powerful and quiet, while the high setting is extremely powerful and only slightly louder than the low. I love that the head is on a spring, has some rotation and give, and ribbed. But I really dislike how BIG the head is. For clitoral stimulation it's over kill. It did give an intense orgasm, it also gave me a numb vagina and thighs. Having said that, I'll still use it often.
Ergonomically designed body, ribbed head, strong, quite vibrations, with a movable head.
