Using powerfully intense dual motors, Cruise Control™ and LELO’s revolutionary SenSonic™ technology, F1s massages you with deeply satisfying sonic waves for an entirely new, completely mind-blowing sexual experience. Or better yet, utilize the free Software Developer’s Kit to create your very own sensations and track your progress – and prowess – through the customizable internal sensors!
F1S Software Development Kit – If you’re an Android or iOS developer with big ideas for the future of male pleasure, Lelo has something extra just for you. With every F1s, you’ll get access to the exclusive LELO SDK which will allow you to tinker with the app, ensuring you get exactly what you want from the accompanying app.
Through its unique dual-motor design, the F1s combines conventional vibrations with an entirely new sensation never before experienced in a male pleasure product: SenSonic™ technology.
Instead of standard vibrations, one of the motors emits powerful sonic waves that permeate deep into your penis, making it feel as though it’s resonating pleasurably from all directions all at once, instead of simply tickling the nerve endings on the surface of your skin. It will help you achieve the most overwhelming orgasms of your life.
Combined with the patented Cruise Control setting, which ensures F1s never experiences a frustrating power drop during vigorous use. Instead, it intelligently monitors and controls the intensity to ensure you get a completely seamless, uninterrupted experience.
