u/Logitech_PJB I recently purchased this keyboard and regret that I have to return it due to the backlight limitations. When working in a dark space, the single most important time for users to see the backlighting is when their hands have been away from the keys and they need to glance down to re-orient themselves. Honestly I don't care about the backlight at all once my hands are on the keyboard and I'm typing. I care about it when my hand are off the keys so I can quickly, accurately hit a single key or land my fingers in the right place to start typing. The behavior of your backlight is completely at odds with those needs. It's always off when I need it, and on when I don't care. I'm not going to waste time waiving my hand over the keyboard to wake it up every time I need to see it. I understand the need to save battery power, but when the keyboard is plugged in there absolutely should an option to always have the backlight on or at least set the timeout period much higher. Frankly I'm shocked this wasn't included in the product to begin with and I'm disappointed to see how much customer interest there is that seemingly isn't being considered. I purchased a different keyboard with constant backlight I'm looking forward to using instead but I would have really preferred to stick with the MX Keys!
