The middle of the vibrator has 3 rows of metal beads below the silicone
outer which when activated rotate and cause the head to gyrate and
wiggle. The vibrator has a protrusion, which is positioned so that it
can tickle and stimulate the clitoris. At the base is the control panel,
which has several buttons to control speed, rotation and type of
vibration. The Ultra 7 Beaver vibrator has 7 modes of vibration,
including 4 normal buzz/vibrator settings and 3 pulsating/throbbing
settings.
