I use this mouse primarily on daily internet works, it does eliminate the pull and push motion caused by using other regular mice. It takes some getting-used-to though. Now I have this one on my right side and the old one on my left side to work both hands when either one gets tired. Amazon picture is B/W, actual item you will receive is with the red scrolling ball. This mouse has been on the market for long time, it is not with advanced technology, but it works and helps. With this mouse, you do not need a mouse pad or large footprint on your desk.
