The Pro Fit Ergo TB450 also features long battery life, patented ball ejection system for easy cleaning, and precision opticaltracking technology. If you’re experiencing issues with your trackball mouse such as stickiness, slowness, or scrolling problems, it’s likely that it needs cleaning. Follow the steps below to clean and lubricate your trackball, restoring its optimal functionality. 1. Remove the ball from the socket using the eject button on the bottom of the trackball frame. 2. Clean the ball and trackball frame with a damp cloth or rubbing alcohol and allow them to dry. 3. Lightly lubricate the ball with a non-acidic lotion. We recommend using an oil-based lotion such as Vaseline for the best result. Evenly rub a pea-sized amount of lotion into the palms of your hands and roll the ball across the lotion on your hands until the ball is evenly lubricated. 4. Gently push the ball back into the socket. If the ball feels a little sticky, simply roll it around in the socket until it moves freely. ## Features - Ergonomic Design - The sculpted ergonomic design and smooth thumb control provides all-day comfort and features a unique 45° tilt that helps improve wrist and forearm alignment - Dual Wireless Connectrion - TB450 includes a choice of Bluetooth Low Energy (LE) and 2.4GHz wireless connection (2.4GHz nano receiver included) - Long Battery Life - TB450 has long battery life means up to 18 months of use with 2.4GHz and up to 15 months of use with Bluetooth - High-Quality Optical Tracking - A high-quality optical sensor accurately tracks the 34mm thumb-operated trackball, giving users smooth cursor control and optimal precision.
