At work, I use a Logitech MX1100. It used to be my personal mouse at home and I have it now for more than 6 years. The rubber on the scroll wheel is non existent though. And the sides are deteriorating ahah.
At home I have a Logitech MX Master for about a year.
Right now I just really can't deal with a computer without the free-scrolling mode that Logitech mice have.
