There's an unpleasant metallic sound coming from the right mouse button, and I can't quite place it, a slight jolt.
I saw somewhere here that someone put foam padding under the keys or something. Could you tell me?
Is it normal that when I scroll the encoder forward, the same unpleasant sound appears, like on a cheap mouse, or is that normal? And can I lubricate it? Or is it easier to just return it and get a different mouse?
