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: the 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.

• Softer and more flexible sleeve for complete comfort
