ElectraStim Flick Duo Stimulator Pack EM80-E

The Flick Duo starts as a soft tingle under the pads and builds, step by step, into a deep, rhythmic throb. Its signature trick is motion. Flick the control unit with your wrist and the current pulses in time, slow and gentle or fast and sharp, so a stroke or a playful mock spank lands exactly when you move.

Each of the two outputs has its own 25-level intensity setting, shown on LED displays, so you can run two areas, or two people, at different strengths from one unit. When you want your hands free, the built-in programs take over, including escalating patterns.

The slim, soft-touch unit measures about 3.74 x 2.25 x 0.75 inches and charges over USB, so you never need batteries. The pack includes four self-adhesive electrode pads, an output cable, a USB charging cable (no wall adapter), a protective pouch and instructions. Only use electro-stimulation below the waist.
