The keyboard is heavy. For some, this may be a disadvantage. Has some pros: - Working hours - No batteries - Design - Automatic backlight when you bring your hands to the keyboard - Quiet - The functional range is configured through proprietary software - Quickly switch between devices Has cons: Minor cons - Does not remember the adjusted brightness of the backlight, after restarting you need to adjust the level again (press the key a couple of times) - Unusual left shift - The backlight is visible from the gaps between the keys (may confuse someone)
