SenSonic & Cruise Control - HOW DOES F1s WORK?

Through its unique dual-motor design, the F1s Redline 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 the bestselling sex toy of all time. Instead of standard vibrations, one of the motors emits powerful sonic waves that permeate deep into your organ, 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 climax 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.
