Review on Macally Wired Mouse: Quiet Click, Adjustable DPI, and Optical Sensor - Ideal for Laptop, Desktop, PC, Chromebook, Mac and Notebook - Light Blue by Jesse Bailey

Very light and easy to use mouse. Very fast and responsive! I like it. It worked right after plugging it in. The problem I'm having and would like to fix (if possible) is that the rollerball doesn't always work for scrolling on a webpage. It's intermittent. It starts running and then just stops. I have to use the up/down arrows to move the scroll bar, then for some unknown reason the movie starts working again. It seems to work well in Word and Excel documents.
