Wrist need a rest? The Kensington Expert Mouse Wireless Trackball has everything you need to make the fingers-only trackball experience your own.

I owned the original Kensington trackball and have been hoping for a current revision for a couple years. This pretty thing arrived this morning and installed easily and without issue on an EVGA Micro2-v3 mb. I use an ultrawide LG at 3440x1440 with it...

- scrolling directly left and right seem difficult at times - scroll ring is loose and feels cheap - ball is actually light weight. a heaver ball would be nicer.

Smooth, accurate tracking Comfortable angle It works. I take for granted the measure of control I expect, until I do not have it. How long it works without problems will tell me about its build quality.

Small complaints: - No Scroll wheel click. - The scroll wheel does not move smoothly. It does not have the ratchet of a normal scroll wheel, more of a rubbing/grinding. Only major problem: This is not your standard mouse, you will have to train your...

the scroll ring took less than five minutes to adjust to, its amazing. comfort pad is kindof nice. good for casual computer scrolling and clicking.

the angle is wayyyy too steep, I have to pitch my wrist at such an awkward angle to operate the overly large ball. Since the wheel is so large, it is not nearly easy to control as a more nimble smaller one. I often find my myself pushing the ball with...

Precise in a way that no normal mouse ever can be. Smooth and precise scroll wheel. Very high quality, I have been using the same trackball since 2010. Much less stress on your hand than a normal mouse.

Requires frequent cleaning, it even needs to be taken apart from time to time to keep it clean.

I used the basic orbit for the past many years, and only ordered this because the buttons finally wore out, using this is a blast compared to it with the added four buttons being remarkably handy and the scroll ring allowing me to play the games I...

I found it awkward using at first due to it's design choice, and after reading a review stating the cushion it comes with for the wrist was rather bad I see why now, it attatches with two pegs that hook beneath the mouse, the pad isn't quite properly...

Bought in December 2007 and it still works well.

The scroll wheel movement always felt a little gritty; I just got used to it.

I've been using one of these for over ten years - yes, the same one! They are built like a tank, and once you get used to one, you will NEVER use a mouse again. This is simply the best pointing device ever made, period.

Expensive - but you get what you pay for.
