Comfort: I initially got a trackball over 10 years ago to reduce wrist pain from using a mouse. Ease of use: Anyone can learn to use a trackball, the cord never gets tangled, the cursor stops moving when you do. Power: You can place pixels exactly (which is why a lot of CAD users have trackballs). Warranty: 5 years! I just had mine replaced because the scroll ring started failing after a year and a half of use. I called Kensington, and they Fed Ex'd me a replacement!


Feels great in hand, buttons feel smooth, great tracking. BATTERIES HAVE LASTED FOR 1.5 YEARS!


It's the only mouse I can use without feeling pain


It has a fast optical sensor, so moving your hand quickly doesn't lunch/stop the cursor in random. Very good for fps games, like Quake and UT series. Because of its simple desing, only 2 buttons and 1 wheel, you never accidently press something as with those fancy million-button maniplators. The cord is thiner than in microsoft mice, which is good. The mouse is light, simple, and reliable.


My wife has small hands and likes this mouse. I don't...it seems to make my hand/wrist tired where my normal Logitech mouse does not.

works on any surface. Just has a very nice feel




Great product!!!


Easy setup works flawlessly good price
