Lelo F1s V3

Ribbed Internal Channel

The internal channel of the F1s V3 is lined with silicone ribs, and those ribs do two jobs. They grip along the shaft for a snug, tight hold, and they let air move through the sleeve so air pockets don't build up. That steady airflow keeps the suction consistent instead of choppy. The ribbing gives targeted texture along the length, and how you hold and work the device changes the feel from gentle to intense. The open, textured interior is also easy to rinse clean between sessions.

Motors, Modes and App Control

Dual motors work together on the shaft and its nerve endings, so no hand motion is needed. The device has four preset modes, and the Lelo app unlocks four more custom settings, including an AI Interactive mode. A built-in performance feedback sensor reads the device's movement and sends encrypted data over Bluetooth in real time. The app then matches motor intensity and motion response to what you're doing. Cruise control holds the intensity steady from start to finish.

• Dual motors for hands-free stimulation
• Four preset modes plus four app-unlocked settings
• AI Interactive mode driven by a real-time movement sensor
• Cruise control for consistent intensity

Material, Size and Colors

The sleeve is made from liquid, body-safe silicone. It's soft and stretchy, and it springs back after repeated use. Insertable length is 4.3 inches. The overall unit measures 5.67 inches long and 2.83 inches wide and weighs about 0.69 pounds, which gives it a solid feel in the hand without being bulky. An XL size adds extra length and width for larger anatomies. Color choices are a bold red and a bright teal, both with the same internal design.

Packaging and Warranty

The box measures 7.4 by 4.3 by 3.1 inches and weighs around 0.70 pounds. Lelo backs the F1s V3 with a 1-year warranty and a 10-year quality guarantee.
