As a keyboard, the Signature Slim Solar+ does what it needs to do, and it does it well. Typing is fast, precise and not too loud. However, I find the keyboard a little too hard and too flat, as the tilt angle cannot be changed.
The Slim Solar+ Keyboard from Logitech is a wireless keyboard specifically designed for professional work. With its modern and elegant design, it offers a comfortable and efficient typing experience. Bluetooth technology allows for easy connectivity to various devices, while solar power ensures that the keyboard is always ready for use without the need for battery replacements. The German keyboard layout provides user-friendly operation, and its compact design makes it ideal for use in the office or on the go. Weighing in at 700 g, it is stable yet light enough for easy transport. The combination of functionality and sustainability makes the Slim Solar+ Keyboard an excellent choice for those who value quality and environmental consciousness.
