Review on Logitech Lightspeed Wireless Adjustable Programmable by Wiktor Niekrasz ᠌

Low price, Design, ergonomics, weight, length and quality of the wire, good software (it is very clear and convenient to customize the keys for yourself), the number of keys is optimal. Separately, I want to say about the wheel, it is divine, it is possible to set up scrolling to the right / left on Copy / Paste and save a bunch of stupid keystrokes. You can set up several profiles with different command options (if you live more than one, it helps a lot).
