I started using a trackball and now I can’t imagine how you can use a regular mouse. I remember that with a classic mouse, there are always red chafing at the bottom of the palm, and over the years, the hand began to hurt. With the trackball, it all went away in a week. Now I'm going to buy the next trackball model from Logitech, because there is not much choice. Expensive and I think that again two years is enough. Logitech actually has a monopoly on this type of mouse. But I do not want to switch to a regular mouse at all.
