Pump Worx Accu Meter Power Pump. Discover thick, throbbing erections that last and last with this professional grade Accu-Meter Power Pump. 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 trigger handle, and watch your pleasure rod swell with power! The soft PVC 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 squeeze of the lever, while the easy to read gauge lets you know how much pressure you have pumped. The tube is made from thick, heavy grade acrylic and marked with both metric and US standard graduations to measure your growth. The precision pressure gauge allows you to monitor your pumping progress and view the amount of vacuum pressure. When you have reached your desired size, simply push the quick-release valve to instantly relieve the pressure and you are ready to play! To prolong ejaculation, slide the included enhancement ring over your shaft until it is nice and snug. The tight squeeze will prolong cumming, help maintain your erection, and extend the fun. When you're done, simply detach the cylinder from the vacuum hose and restore it to like-new quality with Pump Worx Toy Cleaner and warm water.
