"Jack Hammer" is more like it with this thrusting dual stimulator. It has six thrusting speeds, non-jamming beads, three vibration intensities and four variables. It's long and strong, though the insertable length is only about 4 1/2 inches. It doesn't remember settings, but it does have LED lights making it easy to just dial back to where you want to be. And you can take it in the tub with you, so long as you don't have thin bathroom walls.
