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™ the world’s bestselling sex toy of all time. 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.

  • Access to Groundbreaking LELO Tech - Open interface enables you to capitalize on sophisticated, industry-leading technology and shape the future of sex.
  • App Connected - Connect your device to test drive the LELO app - control device settings as well as gain new insight into your performance.
  • SenSonicTM Technology - The mind-blowing sensation of sonic waves and patented Cruise Control technology make F1s the ultimate act of self love.
  • Body-Safe Silicone - Ultra-smooth and soft to the touch, F1s looks sleek on the outside and feels sexy on the inside.
  • Fully Waterproof & Rechargeable - Using the supplied USB charging cable, F1s can go wherever you go, and the smooth, waterproof design is easy to keep clean.

Something different, in an explosive way

Very nice sensation, can keep up with multiple climaxes in one session. App is a little tricky to use, I mainly just stick with the buttons.


I bought this a month ago and have used it a handful of times. I wouldn't yet call myself a power user, but I certainly have found the mind blowing explosions advertised.

I love it

It's amazing. I feel very good about using this product. I love it

Works like a charm

Takes me minutes what used to take 1/2 hour, and without breaking a sweat

Good device, bad app.

I’m not a “big” guy so I like it’s smaller size. It’s nice to have something designed for average size and not some 12” monstrosity that’s bigger than it needs to be. Also it feels pretty great. It’s annoying to me that is sounds like a car when it’s running, I suspect that’s intentional based on the car dashboard design of the app. Cleaning it could be easier, although it’s not too hard. Battery life seems good. The “kit” it comes with is dumb and not at all useful. I’d prefer you knock $5 off the price and save the environment and ditch the kit.
The app is terrible. You can’t have it run in the background which means you can’t use it while also watching video which seems really short sighted for what it’s made for. Overall I’m happy with it and have already adjusted to how to overcome its shortfalls, but it’d be nice if I didn’t have to.
