If you sit at the computer a lot, then you know how important a good mouse is. I purchased the Dynex optical mouse at Circuit City. The primary reason that I got the mouse was that I hate to use a mouse pad. I had heard that the optical mouse is the best if you don't want to use a traditional mouse pad.
My optical mouse is black and silver. There is a center scroll button which saves time on Internet sites and when I am writing long articles.
The right click and left click buttons work great. They are easy to reach and to use while I'm doing my computer tasks.
The only complaint that I have about the Dynex mouse is that it is not ergonomically designed. There are times when I use the mouse a great deal that my wrist does get tired. I didn't think about that part of the design when I purchased it. The next time I get a mouse, I want to get one that is ergonomically designed. Other than that though it is a good little mouse.
