Increase your size and confidence with the easy-to-use, professional-grade Max-Precision Power Pump. 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 expand and swell with power. The clear, vacuum cylinder allows you to see your C*CK 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!
