About the Product
LELO F1S V2 Sonic Male Masturbator in red and black is a rechargeable sonic male masturbator that pairs deep sonic waves with vibration. LELO gave this version a pliable, extra-soft silicone sleeve, a wider range of sonic intensities and four pulsation patterns. Ten sensors track how the device performs in real time and feed that data to the F1S app, so men who enjoy tech-led solo play can fine-tune every session, with or without a phone.
Key Features
- SenSonic technology: Sonic waves create a deep, resonant sensation that reaches beyond surface vibration.
- Dual motors: A sonic motor and a vibration motor work together across four pulsation patterns.
- Pliable sleeve: The extra-soft silicone sleeve flexes around you for a closer, more comfortable fit.
- Cruise Control: LELO's Cruise Control technology is designed to stop intensity dropping during use.
- Ten sensors: Responsive sensors report on speed, stamina and technique through the app.
- Open SDK: Developers can use the iOS or Android SDK to build their own connected experiences.
- Fully waterproof: The sealed body can be washed thoroughly under running water.
Why Choose the LELO F1S V2?
Few male toys are built as an open platform. The F1S V2 works simply from its three buttons, yet it can also connect over Bluetooth for performance feedback and extra control, which makes it a good fit for anyone curious about smart sextech.
The red and black colourway gives it a bold, sporty look, while the aluminium alloy casing and silicone sleeve give it a solid, premium feel in the hand.

How to Use and Care
Charge for two hours before the first session.

Holding + and – together for five seconds locks or unlocks the device. LELO warns that silicone-based lubricants and hand creams may leave the silicone permanently tacky, so choose a water-based lubricant.
After use, rinse with a toy cleaner or wash the sleeve with warm water and antibacterial soap, rinse again and let it dry. Store it somewhere dust-free, out of direct sunlight.

Frequently Asked Questions
Do I need the app to use the F1S V2?
No. The three buttons handle power and intensity on their own. The app is optional and adds performance feedback and extra control.
Which lubricant should I use with the F1S V2?
Use a water-based lubricant. LELO notes that silicone-based lubricants and hand creams may make the silicone sleeve permanently tacky.
How long does a charge last?
LELO lists up to two hours of use from a two-hour charge, with up to 90 days on standby.
Can I wash it under the tap?
Yes. LELO describes the F1S V2 as fully waterproof, so the sleeve can be rinsed thoroughly after every session.
