The only problems I have with the Q6 Max are:

- It's way, way too heavy. Heavier than my Northgate Omnikey Ultra. Like it's more adept as an improvised weapon as much as any keyboard ever was.

- Didn't come with all black enter and escape caps (they were red orange), requiring purchasing an expensive complete replacement set.

Minor areas for improvement:

~ Battery life could be better.

~ Charging takes a long time and I'm unsure if there's a charge finished indicator.

~ Would be nice to have an offline flash update & macro programmer to not depend on cloud-based software that will eventually evaporate like everything else.

I do like:

+ Replaceability of switches as I've tried a bunch, settling on Kailh Box White V2.

+ RGB effects can be turned off completely or show a solid color at low brightness.

+ Native USB proprietary wireless dongle, BT with 3 profiles, or wired.

+ Wired or wireless connection while charging.

+ PC vs. Mac layout as a physical switch.

Can't speak much to most of your complaints (I like my keyboard heavy, planned to change all the keycaps and switches, and didn't get a wireless keyboard), but you can download an offline version of Via to configure it. https://github.com/the-via/releases/releases
