This precision gauge penis pump is guaranteed to make your shaft bigger. It works by creating a vacuum inside the tube that draws blood to the area and holds it there, making your penis thicker and longer than usual. The clear cylinder allows you to chart your progress and the pressure gauge measures your work. The silicone ring is shaped like a woman's lips, making it a pleasure to slide inside while naturally stimulating your erection.
The special no-crimp hose & extra larger chamber make it easy to use.
