Lelo F1s Developer's Kit App Controlled Rechargeable Male Vibrator

The future is now. Outfitted with the same revolutionary SenSonic technology that's already made Lelo's Sona a beloved bedside companion, the F1s is a next-generation app-controlled male vibrator that puts you in total control of your satisfaction.

The F1s combines SenSonic technology with Lelo's Cruise Control setting, so the intensity remains constant while you play. These two technologies combine to deeply thrill your penis from all directions at once rather than simply satisfying the nerve-endings at your skin's surface.

The internal sleeve is made from super soft, skin-like silicone with internal grooves that heighten sensation during use. Watch yourself through the window panel as you race towards the finish, urged onward by the powerful dual motors.

The F1s uses 10 cutting edge performance sensors to report your stats back to you, perfect for kicking your pleasure sessions into high gear.

You'll also receive a bottle of cleaning spray, a 'do not disturb' sign, a pair of fingerless gloves, a quick start guide, a satin storage pouch, a USB charger and a warranty registration card.

It's also completely waterproof for shower adventures and easy cleaning, and works best when combined with a generous splash of water-based lubricant.
