The F1S V2 is Lelo's premium penis sleeve, and the closest thing in the category to a smart device. Two motors combine conventional vibration with sonic waves — sound waves at frequencies you feel rather than hear — so the sensation reaches deeper than surface stimulation alone. Ten internal sensors feed back to the LELO app, letting you customise programs to your own preferences.

Twice the motor strength of the previous model, with a softer, more accommodating sleeve. Worth it if you've already tried entry-level strokers and want something more responsive and tunable.
