We're not sure that Pleasurizer (their term for the small device that puts the Vibe in this Vibrating Masturbator) is a word, put we can tell you that it's quite the little slice of heaven. Fitting snugly into the holster on the Masturbator itself, this bullet-shaped (and cordless, by the way) wonder adds an eye-rolling buzz to your stroke that not only can't be beat, but would be pretty tough to duplicate without copying this toy outright. And the ridges on the inside of the sleeve? Woo, doggie. Battery, lube and toy cleaner included.
