The Hydromax X20 has the same features as the X30 and X40 but is a little smaller, designed for guys whose penis length is 3.5 to 6 in. It uses the newly designed Bellows Pump system, providing better, faster gains. The Bellows system now incorporates a new soft-sealing, full support comfort ring for reduced pressure and greater comfort around the penis base and testicle region. It is also removable for ease of cleaning.
A new Swivel Bellows feature allows for full 360 degree positive rotation for full visual chamber viewing plus inclined angle change option for optimum efficiency when used in the bath or shower. The Super Flow Latch Valve system allows for single hand filling in the shower, making using and positioning the hydropump much easier. 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.
