The popular Penis Vacuum Pump is a great help for penis enlargement and erection difficulty, often referred to as penis pumping. The powerful hand pump has a stainless steel safety release valve with a strong corrugated length of piping that attaches to the top of the clear tube. Simply insert your penis into the opening of the clear tube and squeeze the hand pump to force out the air in the tube to create a vacuum.
As you continue to pump, the tube sucks on your penis and the principle behind all penis developers and penis pumps is to create a vacuum inside the tube which helps to enlarge the blood vessels inside the penis, to allow extra bloodflow. This extra bloodflow makes the penis expand to help give a thicker, harder and longer erection with continued use.
