Using the Fun Factory Mr Boss Vibrator is a breeze. Once you get it home, you can start using it right away. If you're using rechargeable batteries, you can upgrade it with the HYBRID KIT to charge them inside the toy. The intuitive button control makes it easy to turn on and off, and you can press the FUN button to switch between 4 speeds and 6 patterns. The LED charge indicator light will let you know the battery status. When traveling, use the lock function to avoid accidental activation. It's 100% waterproof, so you can use it in the bath or shower. After use, clean it with mild soap and water. Make sure to dry it thoroughly before storing. It's made of body-safe materials, but always check for any signs of damage before each use. Keep it in a cool, dry place when not in use.
