1. No backlight, but! This is the price segment in which it is not implied. Everything is corrected either by additional light on the desktop, or by “squinting”. I cope with this, I didn’t demand backlighting from her, then I attributed it to the minuses “in so far as”
2. Logout button (Win+L) right above Backspace. I agree, controversial. Sometimes you miss (and then, during active and blind typing). But in a month I “flew out” 4 times, and I’m sure that in another month my hands won’t automatically touch it.
3. The disadvantage that everyone is blaming and spitting, but which I turned into a “plus” is the F1-F12 keys. Thanks to the Microsoft Mouse and Keyboard Center on the keyboard, you can remap F4-F7, work with caps, and two additional buttons. The Office and Emoji buttons are not customizable at all, so we miss them. They are dead to me. I assigned the “ate” button to the F5 button. Now the browser, folders, are ated, and the "Track back" does not switch. On the F6 and F7 keys, I set the launch of a graphic editor and video editing software. Comfortable. By pressing two keys you start your working day. A trifle, but nice and really comes in handy. Capslock turned out to be a little wider than on the previous keyboard, and therefore instead of “sphere” I printed “CERA”, because the finger fell on the caps, and not on the “F”. How to cure - just turned off the caps button. Now it simply does not work, and when pressed, it modestly highlights: "The key is disabled."
4. A drawback that I also saw in the reviews, but for which I want to stand up: Yes, indeed, after 5 minutes of inactivity, the keyboard falls asleep and does not respond for 3 seconds at the first touch. BUT! After that, it prints what you typed. So, for example, if you scroll the feed with the down arrow, and blunt it for 5 minutes, and then press the down arrow, the keyboard will wake up, think for 3 seconds and scroll down the page. It's like an example. It also does not affect printing. If you start typing after a break, the text will simply appear 3 seconds later. Therefore, this is not a disadvantage.
