Upgrades : Microsoft Notebook Optical Mouse 3000

I bought this mouse from Staples for 15$ and I have had nothing but great production from it. I have dropped it out of my laptop case many times and it has yet to break. It works anywhere too. I have been lazy enough to actually used my mattress as a mouse pad and it works. I would suggest this mouse to anyone. Like I said, the only downfall is that it won't work with older computers because it needs newer 2.0 USB Ports to work. Works in almost all newer laptops though. Hide Full Review
