The Microsoft TrackBall Explorer sets a new standard in trackballs by combining an IntelliEye optical sensor and an advanced ball design. The IntelliEye optical sensor tracks the movement of the ball 1,500 times per second to give you unbelievably smooth, precise control. This Trackball also comes with a five-year warranty.

In Use
The Trackball Explorer is easier to use than the standard mouse, especially for someone who is troubled with Carpal Tunnel. It takes a while to get used to, but then it is great. Now I would never go back to a standard mouse. It is so easy to roll the cursor to wherever you need it on the monitor. The scroll wheel is easy to use and is a great short-cut. There is less room for errors with the thumb click button. The overall design of the Trackball is more ergonomically suited to the hand and more comfortable to use. The only down-side was that at first I kept accidently clicking the right-click button, but after using it for awhile, that problem went away.

The Trackball Explorer preferences can be adjusted using Microsoft's Intellimouse software, which is super easy to use. I found that the default settings worked just fine for me.

In the world of mouse users, there seems to be a those who are standard mouse users, and those who are trackball users. I cannot speak for the die-hard mouse users, but for those mouse users who have wondered if they might do better with a trackball, or those already using a trackball, I highly recommend trying the Microsoft Trackball Explorer. Once you try it, you may never go back to using a standard mouse again. For those with Carpal Tunnel problems, this trackball is a must have.

  • May not be for die-hard mouse users
  • Side buttons take some getting used to
