I've owned almost every version of the expert mouse, the ease of cleaning this one makes it a superstar. Pop the ball out and just pluck the dust balls out and it's perfect again. Past versions you had to take the unit apart and carefully clean all the dust out, this one is laser on ball. The action is silky compared to past models but note it doesn't glide when you first purchase it, take it out of the box, set it next to you while you're watching a movie and move the ball around in several hundred rotations, it becomes very slick after about 20 minutes of this.


This mouse is good, I paired it with K800 keyboard, it feels amazing in your hand and the buttons are placed well, wheel has a button to roll free or with some resistance.


I got this guy because I was having wrist pain and I have to say that I think it is working! My hand seemed to slide onto it without much of a learning curve. The button configuration works well with the middle click being an added bonus.


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.

Great product!!!



works on any surface. Just has a very nice feel



I have been using a track ball for as long as I can remember. The thought of sliding a mouse around is just strange to me, besides it looks very tiring.
