Yes, this is mechanics, but there is no clear pressing, after which the button works. A light press is enough for the button to start working, you didn’t seem to press it, but it worked. The software is raw, it did not work out normally. The backlight is reflected in the monitor, LEDs just stick out on the reverse side, which are perfectly reflected in the monitor, because they are not recessed into the keyboard case. Wasted money, I will take the usual mechanics.
