Moen Revolution Massaging Showerhead
Even with repeated use, the Revolution doesn't bore. A spinning disk twirls a pulsating column of water right onto sore muscles with surprising strength; a large dial lets you choose the spinning speed from a wide range of settings. Providing even more variety are small rubberized jet sprays along the edge of the head, which can be activated for a more intense spray.
