Great mouse, great support, but the software needs some rework
I had an issue with the leds of my model O wireless. The support responded very quickly and gave me useful advice to fix the problem. The only thing that needs some work put into is the glorious core app. Compared to the first version there are some things missing: The language is automatically set to your system language - in my case in German. Some things are translated, others are not. I would really like to have a drop-down menu to choose a language since I prefer my software in English. The other option missing is the inactivity timer for your LEDs. You can no longer set a timer for the mouse to go into sleep mode.
