ProduktrezensionenKensington Expert Mouse 72359 Wireless Trackball - Black

Nearly perfect

I have mouse shoulder problem so I figured a trackball mouse would help. In general, the trackball mouse is good. It's solid: the ball is big and the pointer movement is precise. The buttons is large enough that you can click without having to look.
However, the biggest problem is the steep incline of the device. Even with the included wrist rest (which is stiff and doest not fit to the device properly), my wrist is always at an upward angle when using this mouse, causing wrist discomfort on my left hand which is not my primary mouse hand within one day. However the discomfort went away the next day. Note that I placed the mouse alongside my keyboard at slightly below my elbows, on my keyboard tray, which is the usual place.
For better experience, download and use TrackbalWorks to configure both mouse pointer speed and acceleration to fast. The acceleration setting is quite important as it helps with the precision of mouse pointer control. If you want more precision, slow down the mouse and you get more control. When you want to move the pointer fast, just whip the ball and the acceleration speeds up the pointer movement.
The wrist rest feels cheap even though is kinda work.
One of the best features of this mouse is, however, the scrollwheel. I know some people think it's noisy and grinding. But to me, it works great. I can scroll without changing hand position. It helps with productivity.

Update (May, 14th, 2017):
Having using it for several months, I feel another followup is justified.
The trackball still works great. The scrollwheel spins without hiccup. My wrist doesn't hurt anymore, seems it adjusts to the inclination.
One month after buying the trackball, I accidentally dropped the ball while cleaning and it got a small nick. The trackball still worked but it jumped a bit when the nick scrolled over the jewel. I contacted Kensington customer service, asking if buying a replacement ball was possible. After a few days, Joyce Mah replied back, asking for my purchase information so he could send a free replacement ball. I told him I didn't have the receipt with me anymore and was willing to pay for the ball. To my surprise, he asked if I could send him the picture of the damaged ball instead. I agreed. After a few days, he said the customer service sent me the replacement ball. A week passed, a package from Kensington arrived and, lo, TWO replacement balls were in the package. I was quite happy. The replacement balls work great.Vollständige Rezension lesen...

Best trackball I have used.

Feels very good and east to use. Large ball and easy to use buttons. Wireless connection, so my desk is neat. The best thing is that it's a trackball so I don't have to chase a mouse all over my desk.

Kensington Wireless Trackball

This trackball is obviously well made, it feels solid, has no sharp corners or edges and I believe, will last me a long time . It feels comfortable to the touch. It is well designed to allow all 4 buttons to be easily reached. I particularly like the back button and scroll ring (Very handy). I would recommend getting the hand/ wrist rest (as I did) it makes it even more pleasant to use for extended periods. I opted for wireless simply for the esthetics of having a tidy, wireless desk.Vollständige Rezension lesen...

Superlative, highly recommended for left-handers.

This is a fantastic product. I am left handed and this is the ideal for me. I can use left and right and for extra precision both. It is comfortable and places no stress on my hand and I do not have to move it around the desk or mouse pad, not placing stress on my injured shoulder. It sits in the one spot on my desk. I use it for graphic design and it is precise. I cannot recommend it enough. Thank you for a super product that is worth every penny of its cost. Compared to other left-handed products this is an absolute bargain. There are not enough superlatives to adequately describe it.Vollständige Rezension lesen...

Used Kensington’s Expert Mouse trackball since switching from right-to-left hand use nine years ago. The smartest mouse by a long way.

Rough construction, poor performance

Ball action is very scratchy, scroll wheel sounds like a dirt road and is as rough as one, speed of action is a fraction of my other trackballs, including other Kensington.
I just ordered an Elecom huge to replace it.Vollständige Rezension lesen...
