In general, I am satisfied with the purchase, I hope it will last like the previous keyboard from Logitech for 8 years. Most of my discomfort, of course, is the result of many years of habit with the previous keyboard from the same Logitech. But still, I would like Logitech to hit its designers in the head, since in the keyboard, the convenience of pressing buttons should not become a victim of designers' attempts to bring "novelty" or "beauty" by equalizing the size of function buttons, but as a result of shifting the top row to side. And no, if you think that no one uses the F1-F10 buttons for their intended purpose, you are greatly mistaken.
