I have both the MX Master 3X Mouse and the MX Master Keyboard. I love how I can switch between computers. However, If I am on Computer 2 and start typing, a lot of the time the Keyboard switches over to Computer 1 and the typing goes there instead. This is especially true if I am logging into Computer 2, a lot of time my Keyboard wiil switch to Computer 1 and wake it up and try to logon to it instead.

Just thought you should know...
