The Bathmate Hydromax X30 is the ultimate in hydro technology for penis development and health. Size: 29 cm tall uncompressed, 22 cm tall when compressed, 5 cm diameter. Introducing the new revolutionary concept in penis development. The Bathmate Hydromax X30 is the ultimate in hydro technology for penis development and health. Does all the Bathmate Hercules does and more. Hydromax generates 35 percent more suction force than the Bathmate thanks to its unique, newly designed Bellows Pump system, providing you with better, faster gains. The Bellows system now incorporates a new soft sealing, full support comfort ring to give you reduced pressure and greater comfort around the penis base and testicle region. As an added bonus, it is also removable for ease of cleaning. A new Swivel Bellows feature allows for full 360 degree positive rotation to give you full visual chamber viewing plus inclined angle change option for optimum efficiency when used in the bath or shower or when you are using the amazing new Hydromax pleasure ring system. A new Super Flow Latch Valve system allows for single hand filling in the shower, making using and positioning the hydropump much easier for you. A new metric and imperial guidance scale gives you improved visual viewing area, plus upper and lower texturing on the vacuum tube for better grip and control. The internal bellows size has been increased and the number of convolutes reduced to allow you to gain even more impressive girth expansion.
