Query: Good Mouse, Great Price

I purchased this mouse as a gift for friends to replace their defunct trackball mouse. (Actually, it was a gift for me, too, because I couldn't stand to use their computer with that old mouse!) They are delighted with it and can't imagine how they lived without it for so long. I was thrilled with the great price and exceptionally fast delivery.
