How Does Penis Pump Work?
To use a vacuum constriction device:

- Pump the air out of the cylinder so that a vacuum is created. The vacuum draws blood into the shaft of the penis and causes it to swell and become erect to give you harder erection or bigger size .
- Once the penis is erect, with the help of lubricant, slide the retaining band down onto the lower end of the penis.
- Remove the pump after releasing the vacuum.
