trackballs

My Microsoft Intellimouse Trackball quit on me after long usage so I bought this one today at Circuit City. It wasn't an easy choice given all the confusing models on the shelves! I prefer the trackball design over the older "moving" mouse which was a real chore for me to use. Initially, the ball moved the curser quite quickly and freely around the screen. However, after about 10 minutes, I noticed myself frequently hitting the left button when I clearly didn't intend to.
Also, my wrist became tense and would cramp up from using it. I think it was due to the wide frontal design. I put my old Intellimouse in its place and found I didn't have the pain nor discomfort. Unfortunately, I can't recommend this mouse based on my own experience with it. I think I'll get another Intellimouse which I would recommend.

I've been using this trackball for over a year now and I love it! I went from the Logitech 3 button mouse to this trackball and it was a very smooth transition! It took no time to get used to moving the ball and clicking the buttons.

I started using this trackball because my dr thought I had the beginnings of Carpel Tunnel Syndrome and I've read several articles that Trackballs are supposed to be more ergonomic for your hand. I don't know if it was the addition of the wrist pads or the use of this trackball, but I have had no problems with my hands since!

There was only one downside to this unit. I have found that this Trackball gets dirty a lot more often than a normal mouse does. I've found myself having to clean it normally once a week. I believe it was probably due to the oils in the hand, etc.. Otherwise, I love it!

It is not the best mouse but you get used to it.
