Sizzling Simon provides an unprecedented vibration and electrical stimulation at once! No cables or devices – Sizzling Simon vibrates, tingles and pulsates all on his own. The E-stims have not one but two vibration motors: one in the tip and one in the shaft. These 2 motors work with 8 different programs and 5 different intensity levels to provoke ecstasy in a wide variety of ways. The E-Stim's conductive surfaces run the length of the toy's body to make the stimulation as smooth and broad as possible. Because 8 vibration modes and 5 e-stim varieties weren't enough, the Mystim E-Stims also have a training program that strengthens the muscles in the pelvic floor –enhancing a woman's ability to reach orgasm. The three different functions are easily controlled via the buttons in the handle. Choose whether to use e-stim and vibration together or only one of them. The E-Stims are not only powerful but also extra quiet and made of 100% medical-grade platinum silicone, making them completely hygienic and easy to clean with a damp cloth and a mild soap. Underneath the silky soft surface hides a long-life, Lithium-ion battery that can be re-charged with the Mystim magnetic charge USB cable.
