The soft spherical head gives a soothing massage, operated by a two speed switch located on the Wand's slender handle. Unlike cordless style massagers, the Magic Wand's strong electric motor is powered using a standard cord/plug, providing a constant power source for those extended massage sessions. Operation lasts about 25 mins with 5,000 vibrations per min. on low and 6,000 vibrations per min. on high.
