During manual masturbation, women will instinctively and randomly change finger pressure, slow down, speed up and move their finger location as they need to increase arousal. It’s very “play by ear”. Zumio has a unique tip, stylus and patented motor clutch drive system, that enables the same natural motion and allows users to dynamically go from high speed and intensity down to a low speed and intensity, without having to touch a control. By comparison, other than some slight variation, vibrators continue to operate at high speed (6,000 – 8,000 RPM) and modes like cha-cha, wave, pulse, etc., presume that all women will respond to a fixed pattern of stimulation. It’s simply not possible to program the stimulation experience as it will be unique for every woman, every time!
