Automatic Penis Pump for Men Erection & Enlargement with 2 * 8 Modes

About this item
【8 Stable Vacuum Modes, Instant Results】 - The first penis enlarger on the market with 8 pressure levels (-350Mbar-0Mbar), providing a more precise range of pressure values for you to choose from to exercise and lengthen your penis. We recommend beginners start with mode 1 and not use the strongest negative pressure directly.
【8 Breathing Vacuum Modes】 - The penis extender also has 8 breathing vacuum modes, mimicking the swallowing sensation. By training scientifically with the rhythm of pressure fluctuations, you can experience a more firm and enduring erection, which will help you perform better during sex games.
【Upgraded Versions, Better Erections】 - We have upgraded this penis pump with the latest generation of intelligent chip and an LED screen, allowing you to visually see the changes in pressure values. Plus, with a transparent cylinder and clear scale, you can easily track the growth and results of your penis exercises.
【User's Guidance】 - First, follow the user manual installation instructions, then select the pressure setting to use. When the desired erection effect is achieved or you feel discomfort, press the third button "O" once or twice to return to the first level of another mode, and then press the fourth button "-" to release pressure or long press the power button to release the pressure in the cylinder.
【Material & Size】 - The main materials of the adult sex toys are body-safe silicone, ABS, and AS. Comes with 3 penis rings and 1 lubricant. Cylinder size: length 20cm / 7.87", diameter: 6.7cm / 2.63", circumference: 20cm / 8".
【Easy to Clean & Ultra Quiet】 - The engine is NOT waterproof, you need to remove it and keep it dry! Please use mild cleaner to wash the cyliner and penis rings. The male sex toy is super quiet to use and will not make annoying noises to disrupt your immersion!
