I had the exact same issue with the Microsoft Sculpt, it would disconnect much too often. There is a setting in Windows that sort of helped it but not fully. I also missed the standard cursor keys placement (home/end/pg) and the number pad as I will often punch in some numbers or even hit the enter key over there just to mix it up a bit.

The Logitech is a full width/key keyboard so cursor manipulation muscle memory is great, that was something I was still getting used to on the Sculpt. The Logitech does not disconnect as much as the Sculpt and there are no repeat key presses, it does however still disconnect at times and it is most obvious when trying to copy or paste. Overall the Logitech is the board I like best since the natural 4000.

If there was pie in the sky I’d like a full key, ergonomic split, wired, and hot swap keys so I can just fix any key that has an issue in the future. I searched high and low for that combination and haven’t found one that checks all the boxes. There are split mechanical keyboards but they are always missing a feature like: not hot swap, short the cursor keys, have shuffled the cursor keys, or dropped the number pad. There is one mechanical keyboard that comes extremely close but the keys are not hot swap.
