PULSE is a multi-award winning penis stimulator that uses high-amplitude oscillations, rather than low-amplitude vibrations, to stimulate. Take foreplay to a whole new level, or turn foreplay into the main event. The inside pulsates for the wearer and the outside vibrates for their partner. PULSE can be used completely flaccid. Tests have shown that PULSE can lead to orgasm even while the user remains completely flaccid. This makes PULSE ideal for those with erection difficulties who need a little extra help. PULSE can be used with or without lubricant. PulsePlate(TM) provides stimulation direct to the frenulum leading to a unique and extremely powerful orgasm. Materials: Silicone. . 100% Waterproof.
