This massager has multi settings for you to use, at 3 intensities.
The device is indeed water proof thanks to a clever way of connecting the usb cable.
Built in Li-Ion batteries with a 12 hour run time. A major plus for long 'sessions'.
Oh, at it comes with a small instruction guide for masturbation.
It's not quiet, but then it's no louder than any competing product. It has VERY bright blue LEDS which flash; it will really light up a room.
Despite the appearances, the motor is located under the silver band, so the entire thing vibrates, and thanks to it's waterproof characteristics, you can use either end for your needs.
The only thing you need to actually be aware of is that the power button MUST BE HELD for 3 seconds to turn the device either on or off. This keeps you from turning it on accidentally in a purse or handbag.
Overall, 5+ stars
