Why did I put away that wireless mouse?

A few years ago, I bought a wireless mouse, used it for a few days, then put it away in favor of my old mouse.  Every so often, like when I’m not feeling the course-prep love and I’m desperately looking for an excuse to procrastinate, I remember that wireless mouse, but can’t remember why I stopped using it. So I dig it out, reinstall it, use it for a while, and then put it away again.  The last time that happened, I decided I would put it away so far that I wouldn’t be able to find it the next time I wanted to try it again.

I want to try it again, but I can’t remember where I put it. And no, I don’t remember why I must have decided the corded mouse was better.
