Pump up the Volume and get to know LUX Active's latest addition! The Volume is an intuitive high-tech penis pump which allows the user to sit back while it does all the hard work - no pun intended - thanks to its incredible automatic mode. Right out of the box, the Volume comes equipped with a USB charger as well as a replacement waterproof ring for the control head. Slip inside from the silicone opening with comfort and ease. The Volume is controlled by three buttons: The power button for turning ON/OFF and switching between modes. The plus (+) button for increasing pressure level. The minus (-) button for decreasing pressure level and air release. Volume has 2 modes of operation to choose from: Automatic & Manual. Simply put, automatic mode allows the user to relax while the Volume works its magic on its own. In Manual mode, the user can choose their desired pressure level. To switch between modes, repeatedly press the power button. On the control panel, monitor everything from vacuum pressure, to the amount of time spent pumping per session. Want to see and track progress? Easily measure growth with the marked measurements along the side of the cylinder. When you want to turn off your device, simply press and hold the power button for 3 seconds. To charge the battery, plug the USB cord in underneath the three control buttons and attach the USB part to a power brick or other power source.
