Enjoy a high-tech design, impressive suction, and incredible comfort with the Master Gauge Penis Pump. Its built-in pressure gauge makes it the premier innovation in pressurized penis pump technology, and its impressive size lets you keep up your pumping routine as you continue to grow to new heights. The penis pump works using a vacuum seal and pressurized suction to increase blood flow to your penis. This creates a harder, firmer erection for you and your partner to enjoy immediately. And, in the long run, it encourages impressive growth in both length and width that your lovers will swoon over. The easy-to-read pressure gauge lets you keep track of how much pressure is being applied to your penis. The clear vacuum cylinder gives you an up-close viewing experience as your penis grows and grows with increased blood flow. Measurements on the side of the cylinder make keeping track of your progress simple. The easy-to-use pump handle lets you apply the pressure to your cock with simple one-handed operation. When you’re done pumping, a quick release valve removes the suction and releases your penis immediately. The flexible, non-crimping hose makes pumping comfortable in all of your favorite positions, and a soft TPE donut sleeve at the base of the cylinder keeps your cock feeling comfortable as you pump. Eight inches of length and 2.75 inches in width are ready to accommodate your firmer, longer, and thicker erection.
