Power is everything, especially when it comes to enhancing and maximizing down there. Got Big Dick (aka GBD) is a penis pump made by PowerBullet® that brings simplicity to the forefront. This battery-operated device is easy to use and assemble. Twist the top cap and remove to reveal the battery compartment. Insert 3 AAA batteries, slide back into place to begin use. Choose between the 3 pressure levels that gradually increase in intensity. Cycle through the pressure levels by pressing the power button. Once all three levels have been cycled through, the pump will turn off. Once turned off, press and hold the air release button to decrease suction and release the seal gently. For added convenience, track growth progress along the sides of the pump, which have included measurements in both inches and centimetres. The top and silicone opening can be removed and re-assembled easily to assist in an effortless cleaning routine. Don`t forget to clean your device after each use with a toy cleaner or with soap and water. Please note, however, that the top of the pump is not waterproof.
