The front part of the keyboard is quite heavy and is very firmly held on the table, you can't just move the keyboard, you have to lift it up. The keyboard has some slope and although I like the flat design of this keyboard it's not annoying and it's not really noticeable, it doesn't have legs. The backlight is visible at an angle and the modes of its inclusion can also cause questions, I turned it off (in the program) and this does not annoy me and will save battery power. Since I've been with Logitech for a long time, I'm used to a shortened left shift and a cropped enter. There are no problems with the shift, I use it without noticing the keys next to it, I got used to the enter for some time, but that was a long time ago, so everything is fine here. The fact that the F keys of the group are grouped more often and there are also silly keys for locking the screen and switching bluetooth modes is not good, but it is not critical for me, although the old FAR is still with me. Prsoto has to once again cast a glance at these buttons and that's it, I think it's a matter of habit. I want to pay a little attention to the kits and keyboard color options. I was considering buying a graphite and black keyboard. And I picked up the MX Master 3 mouse for it. Mice also come in graphite and black. Also, there are versions for Mac and PC, they differ only in that the Mac version does not have a unifying adapter in the kit, I did not check whether they can work if this adapter is connected to them, but I think they can without problems. The keyboard is graphite and black, they differ in the color around the keys, the base, so to speak. The mice are also graphite and black. In addition, they have a different insert in color, where the diode blinks, I think everyone saw it in the pictures. The color of the graphite mouse clearly matches the color of the base of the keyboard; the graphite one looks more gray and faded. A black mouse, it is exactly the color of the keys themselves. And I liked the combination of a graphite keyboard and a black mouse. Good luck to all.
