PULSE III DUO with its remote control and vibrating underside has been specifically designed for couples. While the man controls his oscillations via the device, the remote control allows the woman to tailor the vibrations she receives from the base of the toy. An added advantage of PULSE?s design is that a man does not need to have an erection to use it. Tests have shown that used static, PULSE can lead to orgasm even while the user remains flaccid. This makes PULSE ideal for those with erection difficulties as well as older users who might just need a little extra help.
