Bathmate - Hydromax 8 - Penis Pump - Blue A revolutionary new penis development concept, the Bathmate Hydromax 8 represents the peak of hydro-technology for penis development and health. With 35% more suction than its predecessors and the uniquely designed bellows pump system, the Hydromax promises better and faster results. The addition of a soft-sealing, fully supportive comfort ring around the base of the penis and testicles provides less pressure and more comfort, while the removability for easy cleaning is an added benefit. The Swivel Bellows allows 360 degrees of positive rotation for full visibility and optimal efficiency, especially in the bath or shower. The new Super Flow Latch Valve system enables one-handed filling, while a metric scale and texture on the top and bottom of the vacuum tube ensure better grip and control. With an enlarged internal spring bellows and fewer overlaps, the Hydromax offers even more impressive girth enlargement. Minimum penis length: 18 cm Maximum penis length: 23 cm
