F1s V2 - Sonic Performance Sleeve
Sensation carried through the tissue rather than across the surface
A masturbation sleeve that works by sonic waves rather than simple vibration — sensation carried deep through the tissue, not just across the surface.
Two motors drive SenSonic technology through four programs of seven patterns each, and Cruise Control keeps the intensity constant under grip pressure. The device senses when you are inside and begins on its own; the pliable inner sleeve flexes for comfort, with an insertable length of 4.3 inches.
Ten internal sensors report performance data to the companion app, and an open SDK is available for those inclined to build with it.
Clean the sleeve after each use with warm water and a mild cleaner. Covered by LELO's one-year manufacturer's warranty.
