Pump Worx Digital Power Pump. Take penis enlargement into the cyber-age with our most advanced Digital Power Pump ever created! After only a few uses, you'll discover thick, throbbing erections that last and last. Developed as a safe, affordable, non-surgical alternative to expensive medical procedures and pills, this handheld penis pump is the easy way to instantly enlarge your penis without any negative side effects. Simply insert your penis into the vacuum cylinder tube, squeeze the Easy grip handle, and watch your pleasure rod swell with power! The stretchy TPE sleeve forms a perfectly tight seal against the skin and creates a powerful vacuum inside the chamber, forcing your erection to quickly expand its length and girth. The clear, vacuum cylinder allows you to see your cock get bigger and fatter with each pump, while the LED digital gauge lets you know the pressure. The tube is made from thick, heavy grade acrylic and marked with both metric and US standard graduations to measure your growth. The digital pressure gauge allows you to precisely monitor your pumping progress and view the amount of vacuum pressure. When you have reached your desired size, simply push the quick release button to instantly relieve the pressure and you are ready to play! Use the included enhancement ring to help maintain your erection and prolong ejaculation. When you are done, simply detach the cylinder from the hose and cleanup is a snap with Pipedream Toy Cleaner and warm water. Vibrating penis pump requires 2 N batteries, not included.
