Review on Keyboard + mouse set Logitech MK850 Performance, black, English/Russian by Janis Janis ᠌

1. Combinations of increasing and decreasing the volume are stuck; to stop the "jamming," you must either switch modes or remove the batteries from the device. 2. the connection between the computer and the keyboard is intermittent, but there are no problems with the mouse. 3. The connection will become unstable and the mouse will move in a jerky fashion if there is a wireless antenna or router in close proximity to the receiver. 4. On the third day, the Esc key began to be pressed without being fixed, and it eventually broke. 5. The combination of the PrnScr key and the Fn function is incredibly inconvenient 6. Since the keys from F1 to F12 are not organized into groups, I was surprised to find out that this might be such an inconvenience. 7. Noisy, noisy.
