Plenty of power. Quite a bit bigger than I expected, but that's no bad thing. The long vibrating tab covers all of the inner labia and clitoris with its soft bobbles driving wife crazy. In missionary position I've worn upright to stimulate the clitoris with the long vibrating tab and upside down to give more stimulation to the anus. When in doggy position this is reversed. Long tab upwards for anal stimulation with it's large size and flexibility making it possible to even get a little penetration. Inverted allows her to grab the long tab and massage her own clitoris. So much pleasure is given to her by simply fully penetrating her with my penis and gyrating a little to let the device do all the work. Either party can take hold of the remote for control so it's not just for the wearer to decide the speed. My only criticisms are that the speed dial is a little sensitive making mid-range speeds a little finicky. Also it's a little noisy at high speeds. Takes AA batteries which are often plentiful in the house. Overall well worth the money.

Arrived today and used it today. Bigger than what I expected, the vibrations are powerful and the vibrator for the balls can be taken out and used else where. Definitely recommend, first time using a cock ring too. Great for the price. Both me and my partner love it and will be using again to spice things up in the bedroom.
