Key configuration is nice, but your presets are all stupid and useless and left me feeling like I was going deaf because it was reducing volume without any notifications.

Also, logi options is a resource hog.

Finally, the keyboard has occasionally just shut off. Can't turn it back on until I restart computer. So your hardware is weird too. Might be a bluetooth driver in my pc, but can't figure that out because your software doesn't track erors. Also seems weird since my other bluetooth devices continue fine. So it's something about the keyboard and my pc.
