Lovely keyboard

Having used other Keychron keyboards for some time, I love the quality (although I prefer better availability for some popular models).
The K3 Max is a fantastic keyboard. It is truly responsive, with low noise levels. The keys are easy to find if you are already used to a Keychron setup,
Personally, I score it 4 out of 5 (it would be 3.5 if there was the option) because I sometimes find the lack of non-backlight shine hard to use, and I prefer a darker room setup.
Overall, this is a fantastic, responsive, compact keyboard with some of the past flaws corrected.
Additionally, I am not thrilled with the keycaps' color. They feel too grey; I would love something like the K4 Pro color scheme.
