LELO F1s Prototype is revolutionary sextech console that connects SenSonic and Cruise Control technologies for ultimate pleasure. It has two powerful motors but it doesn’t desensitize users.
  • F1s Prototype vs F1s Developer’s Kit – If you are a developer and would enjoy the open interface offered by LELO, the F1s Developer’s Kit is for you.

  • App Connected – Connect your device to test drive the LELO app – control device settings as well as gain new insight into your performance.
  • SenSonicTM Technology – Thanks to its unique dual motor design, the F1s combines conventional vibrations with a totally new feel never before experienced: SenSonic ™ technology.
  • Body-Safe Silicone – Ultra-smooth and soft to the touch, F1s looks sleek on the outside and feels sexy on the inside.
  • Fully Waterproof & Rechargeable – Using the supplied USB charging cable, F1s can go wherever you go, and the smooth, waterproof design is easy to keep clean.

An exclusive LELO breakthrough, SenSonic technology offers 360 degrees of pleasure. Instead of standard vibrations, F1s emits powerful sonic waves that permeate deep into your penis, making it feel as though it’s resonating from all directions all at once. And with the LELO app, you can adjust the intensity to your liking.


Cruise Control™

Cruise Control is designed to detect any slowing motion of the main motor and can boost the power up again via PWM (Pulse Wave Modulation). In doing so, Cruise Control ensures that you enjoy consistent power and intensity, no matter what. Control this and other device settings through the LELO app.
