Introducing LELO’s brand new male pleasure concept. Bridge the gap between science and nature with F1s, the next generation pleasure products for men that makes you the master of your destiny. The innovative design of the Red version gives you the most pleasurable experience by seeing yourself in action that is happening. 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!

How does F1s work?  

Through its unique dual-motor design, the F1s Prototype and F1s Developer´s Kit RED combine 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.
