Review on Renewed Logitech MX ERGO Advanced Wireless Trackball for Windows PC and Mac by Amar Amar ᠌

Its pros: I liked it very much. Does not play, the buttons are pleasantly pressed. The charge lasts for about a month, is actively used. I got used to it in about an hour. Wrist pain gone. Got cons: You have to clean the area where the ball is inserted once a week, otherwise it starts spinning badly, but this trifle takes about two minutes in time.
