Today we're going to take a look at one of my personal favorite lines of productivity mice: the Logitech MX Master series. I have used the MX Master mouse since the first release back in April 2015. I have since graduated up through the ranks with the MX Master 2 and subsequently now the MX Master 3. While there weren't massive differences between the Master 1 and 2, there are quite a few welcome improvements to the Master 3. We'll go over them here shortly. The MX Master 3 is targeting the professional market in my opinion. Let's see how this one stacks up in the lineup.
