A clever and very useful tool of pleasure for the man who is serious about his equipment. The Top Gauge Penis Pump comes equipped with an industrial-grade pressure gauge. While you are pumping the pistol-grip handle, you can monitor your pumping action with an easy-to-read gauge that lets you know what level of pressure pleases you best. The slightly flared base makes for a nice, comfortable fit and the latex sleeve creates a nice snug environment. Just slide your Johnson inside and feel the suction pump it up! The quick release safety valve makes exiting this penis pump as easy as flipping a switch. Safe, powerful and easy to use.
