CONSTANTLY losing bluetooth connection to my M1 MacBook Pro. MX Keys and Mouse randomly become totally unresponsive, and NOTHING will wake them up. Switching back to Apple Magic Mouse, as the ONLY thing worth paying for (and the degree to which you IT geeks don't understand this simply boggles the mind) is RELIABILITY. I don't want ANY of your bells; whistles; "features"; "neat stuff"; "could do's" — JUST reliability. And this appears simply not to be a priority for the teenagers and twenty-something coders at Logitech. Stop listening to your marketing simpletons and start listening to your customers. Until this happy day, I will be avoiding Logitech products.
