Using your CalExotics Premium Bionic Dual - Pulsating Anal Probe is a breeze. First, make sure it's fully charged. You can use a USB cable to charge it for about 2 hours. Before use, apply some water - based lubricant on the probe to make insertion smooth. Turn it on and start exploring the 7 different vibration functions and dual pulsating action to find what you like best. The memory chip technology will remember your last setting, so you don't have to start over every time. When you're done, turn it off. Clean it with warm water and mild soap, then dry it thoroughly. Store it in a cool, dry place. Remember, always use a water - based lubricant and don't share your probe without proper cleaning to keep it hygienic and in good condition.
