Summary: This is like the newer ones I have used without the extra side buttons. I like this controller much more than using a mouse, but I notice that after awhile the ball does not roll as smoothly as when it is new. It is not very easy to take apart to clean either.
Summary: I'm a big fan of trackball mice and have owned a few different models and this one is a very solid option if you don't want to dish out a lot of money for the high end ones.
Pros: I have been using this mouse for more then 4 years and it is still very responsive. Usually the ball on the mouse would not roll smoothly after as much use as I have put on this one. It's long design fits my hand very well. Good support for the inside of my palm
Cons: Limited Features and the two secondary buttons are not placed well.
Summary: The design is completely different from conventional mouse. It does take getting used to and will make using the old style mouse more difficult where it is necessary. So far, new mouse works very well.
Summary: Have not used a regular mouse in over 10 years. First logitech trackball I had was a Marble FX Optical Wireless, unfortunately they don't make those anymore. Having used a trckpad for a couple of years, I get cramped fingers and was ready for a trackball again.

Cons: No scrollwheel, of-course knew that when buying. Wish the scroll ball was somewhat larger for more precision. Small buttons are hard to get to.
