Through its unique dual-motor design, the F1s Red combines conventional vibrations with an entirely new sensation never before experienced in a male pleasure product: SenSonic™ technology.
It’s the same high-tech concept that made the LELO SONA™ one of the bestselling sex toys. Instead of standard vibrations, one of the motors emits powerful sonic waves that permeate deep into the 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 the skin. It will help people achieve the most overwhelming orgasms of their lives.
Combined with the patented Cruise Control setting, which ensures F1s never experience a frustrating power drop during vigorous use. Instead, it intelligently monitors and controls the intensity to ensure you get a completely seamless, uninterrupted experience.
