I own a MX Master 3S now for 2 years.
And I have to say your software is totally useless. Software works for 1 day and you have to reinstall it.
It is totally unreliable, more worse as junky RAZER even!!!
How can you make such good hardware and totally useless software??????
Dozens of times I installed this software on two machines with identical results.

I do not want to get contacted back.

Thank you.
