I recently bought the MX Mechanical keyboard. I feel like I have been jabbed with a cheap knock off with issues from the onset.
1) The backlight. It turns momentarily if I engage it in the app. Intensity is lousy at best intensity both plugged in or not.
2) Not backward compatible with unifying receiver Logitechs answer to neverending receivers.
3) Keyboard doesn't work wired.

Overall dissappointed, not what I expected from Logitech. Your great claims on battery life don't mean anything to me if I don't have a good product to begin with. Sorry so negative but if I am not honest you can't improve as evidently you don't get real world input from your teams.
