This mouse is an HP...go figure.

Oh, well - I'll gladly right-click for the opportunity to scroll down a page!

And hint - when the batteries give out, replace them with Energizer Lithium AA batteries. They last forever! (I use them for my digital camera now - and they are STILL great after a few months. I used to have to recharge the rechargeable ones every WEEK. And they were MADE for items like the camera)
