Negative Positive
Title: A great product!
Review: I've used one of these trackballs for years now, and bought the new one for a new computer - I wasn't about to part company with my old one. If you have a big hand, you might find this a bit smallish, but I have a small hand and it fits me perfectly. It has been super easy to clean and care for, and never given me any trouble at all. I had to go to the Logitech website and download the driver file to work with Windows 7, as the file that comes on the CD is an older version, but the site is very user-friendly and I had no trouble finding what I needed and downloading it. Once it was downloaded, I reset a couple of the button settings, and that took a moment to figure out, but I finally got it set up just the way I wanted. If you are running XP or Vista, the driver file that comes on the CD will work just fine for you.
Is the review positive or negative?
