Product reviewsMicrosoft Trackball Explorer 1.0 USB Ps2 Ergonomic Mouse X05-87473

Ball would not move - seems like bad quality

The ball in the mouse would not move. When I finally was able to get it to move, the mouse scratched the surface of the ball.

It makes this awful scratching sound when I move the ball now.

I will look around for a replacement ball. I popped a ball from another Trackball Explorer mouse that I own, into this mouse, and while the mouse moved a lot better in the socket, there was still a small scratching noise.

Not happy - I am pretty sure I wasted $80+ on this mouse. It seems X05-87473 is NOT close to the X08-70390 in quality.

Update 10/01/2019 - I purchased another roller ball. It happened to be in excellent condition. I put it into this Explorer mouse with the Part Number X05-87473, and it now works fine. No scratching noise. Have to adjust rating, but still a little disappointed that that the original roller ball that came with this Explorer Mouse was pretty defective.Read full review...

Best trackball

Sad they stopped making these, my original died after sixteen years, and this replacement was in perfect condition. I'd forgotten how smooth the ball was supposed to be. Definitely the most comfortable trackball ever designed.Read full review...

Highly Recommended!

I have been using one of these for the past 20 years, since they came out with it. My other one just got old and started taking a lot of effort to roll the trackball in the mouse. The new one works perfectly!!Read full review...

Good over-priced mouse

It is not better than .expected. I already had one and wanted a back-up.
