Using the Calexotics Eclipse Wristband Remote Rimming Probe is easy. First, make sure the device is fully charged via USB. You can use it in or out of the water as it's waterproof, so a bath or shower can be a great place to enjoy it. The suction cups on the base allow you to attach it to a smooth surface for hands - free use. Put on the wristband remote and use it to control the 12 different functions like vibration, pulsation, and escalation. You can use the probe alone or with a partner for added fun. The memory chip will remember the last function you used, so you don't have to keep searching for your favorite setting. When you're traveling, use the travel lock feature by holding the button for 3 seconds to prevent accidental activation. To maintain the probe, simply wash it with mild soap and water after each use. Keep it in a cool, dry place when not in use. And remember, always use it with a water - based lubricant for a more comfortable experience.
