Pump Worx Max-Precision Power Pump

From the manufacturer:

Discover thick, throbbing erections that last and last with this professional-grade Max-Precision 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 pistol-grip handle, and watch your pleasure rod get bigger and thicker than ever before! 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 and swell with power.

The clear, vacuum cylinder allows you to see your cock get bigger and fatter with each squeeze of the lever, while the easy-read gauge lets you know how much pressure you've 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've reached your desired size, simply pull the quick-release trigger to instantly relieve the pressure and you're ready to play!

Use the included enhancement ring to help maintain your erection and prolong ejaculation.

When you're done, simply detach the cylinder from the hose and cleanup is a snap with Pump Worx Toy Cleaner and warm water.
