Meant to contain the tip and part-way down the shaft (for most men), the Vibration features a soft, non-detailed entry at the end of an ergonomic handle. Inside, sexy tongue-inspired swells and the deeper length beyond shiver, shudder, shake and pulse with those 14 patterns of vibration. More than a surface buzz, the vibration is deep and throbbing, with two motors sharing the work. Many of the available vibration rhythms send pulses flowing between the two for a totally toe-curling stroke or suck effect.
