Hydromax

The Hydromax penis pump is the easiest to use on the market.

To use, you must first warm up, gently massaging the genital area to relax the skin.
On the Hydro and Hydromax series, make sure the valve is in the closed position and remove the comfort fitting (optional). Then fill the pump with as much water as possible, making sure it's just lukewarm and not too hot.

Then simply insert the flaccid penis into the Hydropump and press the pump against the body to create a comfortable seal, ensuring that the testicles are below the seal.

For Hydro and Hydromax models, pulls the pump into the body to create a vacuum seal. Once the pump is sealed in your body, continue the pumping process until you reach the maximum but comfortable pressure.
For the HydroXtreme, you pull the pump into the body to create a vacuum seal and squeeze the hand ball to create more suction and repeat until you reach a maximum comfortable pressure.

Wait up to 3 minutes for Hydromax to do its magic!

You can then repeat the process two more times for the recommended daily use of 15 minutes.

To remove the pump, depress the clear valve cap and hold until the vacuum is released, then safely remove the pump.
Then you will need to massage the penis with both hands gently up to the glans. Repeat this for a few minutes to allow the penis to relax and return to a flaccid state.
