Using MX Master 3S mouse with bolt at home and at work.
Already a 3rd unit with which I experience regular issues with hanging-struggling-jumping cursor due to Bolt connection issues (cursor becomes unusable), even if connected at very short distance between mouse and dongle. So it appears to be a systematic design issue, not dependent on computer or ambient EM fields (or just too prone to typical disturbances).
I would expect getting some firmware fix. But this does not happen for a year, so feels like it is permanent hardware issue. So unfortunately, with all its good ergonomics, MX Master 3S + Bolt does not work as expected and rather not recommended. When tried to get some support, I was literally ****** off, this bad it was, just wasted time. I wouldn't buy this 3rd unit, just got it again from my new employer.
