Using the Calexotics Optimum Series Rechargeable Waterproof Pump is easy. First, make sure the pump is fully charged via the USB cable provided. It takes about 2.5 hours to charge, and then you can enjoy 160 minutes of high - speed stimulation or 180 minutes of low - speed suction. Place the pump over the penis and the silicone donut base will form a tight seal. You can choose from three suction speeds according to your preference. Press the buttons on the easy - touch controls to start the pumping process. When you've reached your peak, press the quick air release button to decrease the suction or break the seal. As for maintenance, since it's a maintenance - free stimulator sleeve, you don't need to do much. Just clean it gently with mild soap and water after each use. Make sure it's completely dry before storing. Remember, it's body - safe, unscented, and phthalate - free, so you can use it with confidence. Regular use of this pump can help you increase stamina, enhance size, and amplify sensation. Keep an eye on the incremental measurement marks on the cylinder shaft to track your progress over time.
