An electronic vacuum pump with 3 suction modes, designed for use in water or with water. Its basic principle is to use the force of water, or rather the water's incompressibility, to increase the length and width of the penis. Of course, the vacuum pump can also be used without water. Using it in water makes the pressure more natural and even, and the warm water inside the cylinder provides a sensationally pleasant environment. It can also be used as a masturbator without using the vacuum mode.

The transparent cylinder has a measuring device in centimetres and inches. The pump has three control knobs. Press the blue button for 3 seconds, the button lights up and the pump "unlocks". Press the centre button to create a vacuum in the cylinder. There is a valve at the top where the motor pumps water or air out of the cylinder. By further pressing this button, the pump's power changes, the intensity of the vacuum generation increases more rapidly, there are three speeds in total, or speed steps if you like. When you have reached the right vacuum for you and want to keep it in the cylinder, press the blue button briefly. To quickly reduce the vacuum in the bottle, press the third button at the bottom.  The pump has a rechargeable battery. USB cable included, charging via magnetic contacts. The battery is fully charged after 2.5 hours of charging. It can then operate for 160-180 minutes, depending on the vacuum level used. The blue light flashes during charging.  Regular use of the pump will keep your penis in shape - your erection will be long-lasting and sexual pleasure will be maximised. Recharge the battery after more than 6 months of storage.
