Pros below: Convenient, switchable backlight, remembers the state and there is no need to turn off the backlight constantly or re-set DPI after turning on the computer, the color matches very well with the rather popular A4Tech KV-300H keyboard, which I also purchased not long ago Cons: The wheel apparently has a lot of backlash, as it rattles quite loudly when scrolling, especially if you turn it away from you, the screws are located under the legs, so you can’t open it and clean it well without replacing these same legs, and apparently they aren’t on sale either, which if they are worn out, it will come out too sideways in the end the software is automatically installed on the C drive with Windows without demand, and by itself it is a little blunt, it doesn’t start the first time, it takes a long time to load (I’m talking about Armory 2, the other one, the one that Create is even worse and even more cumbersome)
