First impressions:
Keyboard arrived yesterday, and I’m very happy with it. The keys are basically identical with what you find on the larger MX Keys - a few differences in layout naturally, but the same feel. No flex whatsoever that I can detect. Stable and nice build, as usual for most Logi products.
Logi Options software gives us nice customizability as well. Backlight needs to be turned down in a lit room which saves a lot of battery.
I paired it with a MX Vertical mouse as well, hoping that can help my shoulder pains. Getting it closer is also a great improvement for me. I still love the big one for number entry tasks, but the MX Mini will probably be the main driver for me now.
