Powerful pumping and suction impulses create an automatic, rhythmic up and down motion of the flexible soft sleeve on the penis, further enhanced by the integrated pleasure ring. The stimulation is individually adjustable: 5 intensity levels and 5 speeds provide 25 different variations. The suction impulses per minute range from 42 in level 1 to 109 in level 5. At the same time, the suction power increases from 16 W to 30 W. Simply apply plenty of water-based lubricant and insert the penis halfway into the flexible, pleasantly soft sleeve, set the desired intensity and speed, and enjoy.
