I pre-ordered and purchased this when it was first released, but I haven't had much opportunity to use it, so I'm putting it up for sale. I don't think there's much sign of use on either the mouse or the pad, but the mouse's sole does show some wear. The sole is still only scratched and not worn down much, but I recommend replacing it if you're concerned. The mousepad was stored after being used a few times, so it has the curling as shown in the photos, but I think it will disappear with use. Both the mouse and pad have been disinfected. Please refrain from purchasing if you are sensitive to used items.
