The PSX08 pump has a transparent cylinder with a gauge, ideal to check how your penis grows with each thrust. But this pump goes further, it has an LCD screen with which you can control the rate of pumping. To start enjoying, you just have to press the + button, after which the screen will light up. Press + again to enjoy the first level of pressure. Keep in mind that the negative pressure will gradually increase, when it reaches a value of -125Mbar, the pump will stop automatically. Once the pressure reaches -50Mbar the pressure will rise again to -125Mbar. When you want to change the level you just have to press + and enjoy 3 more levels. To lower the level, press the - button. Keep in mind that if you are in the first level and press - the pump will turn off. When you think you have grown enough you can press the Valve button to release the pressure instantly. You can combine your pump with the brands vibrating accessory (BO-086) and with the sleeves (BO-084; BO-085; BO-087). But if that was not enough, we include a silicone penis ring to increase pleasure. To achieve the best results, these pumps use the vacuum system, which causes the blood to concentrate on the penis, whether it is flaccid or erect. If the penis is flaccid, you will achieve a perfect erection through a tight and comfortable seal located at the end of the cylinder, at the junction of the penis with the pubis. You can clean comfortably and safely by removing the cylinder from the rubber. Remember to properly clean your pump with a good toy cleaner (N-507) and use your favorite water-based lubricant (N-506) for a crazy, super wet night.
