This rechargeable plastic pump with an easy-to-use suction system draws blood into the penis. Just push the on button and click up for as much suction as you would like. There is a button to release the suction. At first, take it slow until you are used to the pump and know exactly what you need. A constriction ring (not included) helps to maintain the produced erection. Made from medical grade silicone and high quality ABS plastic. The charge lasts 3 hours. 

PLEASE NOTE: Vacuum pumps do not increase the length or girth of the penis permanently. They simply facilitate erection by drawing blood into the penis quickly.
