Vacuum Auto Electric Penis Pump with Precision LCD Digital Air Gauge for Men

Supersize what you've got. 

This automatic penis pump features a sophisticated LED screen for easy-to-see results. Just push the simple control buttons, sit back and let the pump take care of the rest.

Measuring points on the transparent sleeve also let you track your progress while the quick-release safety valve offers instant relief. 

Instructions for use

Lubricate the inner wall of the cylinder and yourself.
Insert your penis into the cylinder. The cylinder should remain firmly pressed against the base of your penis to keep air from escaping.
Slowly begin to work the pump. There will be a slight sensation as air is drawn from the cylinder. For beginners, it is important to start this process slowly to avoid discomfort. Remember to press the safety release valve if the vacuum becomes painful.
Continue pumping/releasing air until you've found a level of vacuum suitable for you: the penis should look swollen, but should not hurt.
Now make sure no air escapes (unless needed) and wait 20 minutes. You may need to pump further during this time to keep an appropriate amount of vacuum in the cylinder.
Once the session is complete, you should appear thicker/longer and have heightened sensitivity.
