Wand vibrators typically  look like back massagers and plug into the wall.  Many new generations are now rechargeable. These wands deliver such an intense vibration, they are often the right prescription for pre-orgasmic women to help them achieve their first orgasm.  They can also help postmenopausal women bring their libido back.  Pleasure-amplifying attachments are made specifically for the ball-shaped head and are designed to hit the g-spot.
