I have a literally brand new Razer Mamba gaming mouse for sale. I had one before this, but my friend broke it so I sent it in under warranty, and they sent me this brand new one. However, by the time they got back to me, I had already bought and fallen in love with a different mouse.
Never been plugged in, battery never used, cords never touched. I received it wrapped in bubble wrap, and it has stayed that way.
