Got pros: High-quality materials and construction, a simple, compact design that is stable on a table, a pleasant weight, excellent Bluetooth performance, nice software with customizable function keys, and USB Type-C charging (a minor plus, but it's nice when all devices on a desk can be charged by the same cable, including a phone, power bank, headphones, and now a keyboard). various drawbacks: 1. The left Shift has been lowered in size for utterly unexplained reasons. This was done so that one additional button with keyboard-like symbols may be added to its space. This is neither a reasonable nor an ergonomic solution. When printing and constantly using the same Excel, the left font is used. You miss and click on the symbols out of habit. However, the Russified version of the smartphone is the only one that uses this wonderful idea. The non-Cyrillic version is constructed using two full-sized Shifts, one on each side. Even the Start and Fn buttons are bigger than the left Shift, for clarity's sake. What is utilized more frequently? I believe the solution is obvious. This is a significant flaw that ruins the overall perception of the device's ergonomics. 2. The keyboard backlight only illuminates when hands are moving; when hands are stationary, the backlight eventually goes off. Therefore, you will need to move your hands to turn on the dimmed backlight if you are sitting still while waiting for a computer task to finish or simply thinking while typing. If Logitech is reading this, I'm confident you can correct this in the next meal. Please make it possible to permanently activate the backlight rather than just when anything moves.
