5.0 out of 5 stars Excellent, December 15, 1999

By	Matt (Jersey City, NJ USA) - See all my reviews

I own three of these - one for each computer I regularly use. They last forever, and never even need cleaning as they never get jumpy. There is never any slippage, so it works much better than a ball-based mouse for things like Quake where you may want to make fast but precise movements.

There are four buttons which can be programmed to do whatever you want. For example, I set one of the extra buttons to be the back button in my web browser. Now I can move through web sites one-handed without having to move the pointed up over the back button constantly. This also allowed me to switch my IE toolbar to use small icons with no text labels, freeing up screen space.

The only possible suggestion I can come up with is that it would be nice if they added on a scroll-wheel like all the new mice seem to have.

I'll never go back to using regular mice as long as Kensington keeps making these.

3.0 out of 5 stars good idea - needs improvement, January 21, 2000

By	Janine Laporte (toronto) - See all my reviews

i love the fact that it has 4 buttons and you can program "button chords" to do stuff. eg. if you press the top two buttons, the current window will minimize. it offers a lot of useful shortcuts allowing you easier access to the taskbar, cut/paste, common keystrokes or your own list of favourite applications.

on the downside is the trackball shape; it is not made with the shape of your hand in mind as it is curved up at end so you can't relax your fingers properly.

also, the NT support isn't up to snuff. i demolished my system when i installed a new driver overtop of the old one (take it from me - make sure you UNINSTALL the old one first!) the technical support people were not helpful or sympathetic with my plight so you may notice some lingering bitterness in this review.

5.0 out of 5 stars Sweet little number, April 12, 2001

By	"blittler" (Denver, CO United States) - See all my reviews

This is an excellent trackball. I have used it for some time now, and until I picked up a MS Trackball Explorer, this was my favorite input device. While I enjoy some of the "advanced" features of the Trackball Explorer, such as optical sensors (no cleaning!), scroll wheel, and ergonomic shape (this is a great piece for web surfing), the Expert Mouse still has a special place in my heart. :) For longer periods of use I generally prefer it, and the large ball makes my hands happy. Also, tech support is PHENOMENAL, far better than MS. In fact, I had to replace my expert mouse not long ago (5 yr warranty!) and they happily sent me out a new one. No RMA, no return, no _anything_ except "we'll send one right out". And they answered immediately. Most of the time with computer tech support, I don't even bother, and either try to fix it myself (easier said than done w/ hardware) or just bite the bullet and replace it. In this case, it was a pleasure to call. If I could give an add'l star for "extra credit", this trackball would rate a "6".
