Summary: Finally threw mine in the garbage. The wireless goes off and on continually - a constant battle of resetting and resetting. I LOVE this type of trackball and have never had a problem with the wired version which is what I went back to.
Summary: Really looked forward to the promised ease of use but this thing drives my wife and I nuts. Surprised we haven't thrown it somewhere, but that day may come soon. The ball is very inaccurate. Moving the cursor with the ball (it's the only way) takes twice as long as our other mice, because it is so inaccurate. And the cursor needs to be moved whether writing, browsing, or retouching photos! Once I get the cursor in the right spot - it will then move - on it's own!!!!!
Huge disappointment (both product and Logitech customer service)

Summary: I'm really disappointed with both this product and the response I've rec'd from Logitech's customer service. If I could rate it lower than a one-star rating, I would. After purchasing this cordless trackman in December '09, it quit working in January '10. I contacted Logitech for a warranty replacement (January 25, 2010), and, as of Feb. 27th, I'm still waiting for a replacement.
Summary: I just bought this for my windows7 machine; the mouse will not work from more than six inches away from the base unit. I'm not sure if this is just a defective unit. Also the plastic construction of this mouse is really cheap feeling; definitely a dated piece of hardware and I'm surprised logitech hasn't updated it.
Summary: I would like to say my experience has not been a good one. I bought this cordless mouse so I wouldn't have cords running across my living room. I have my computer running through the TV,and I sit I about 6 feet from the screen. I have the same corded model, and thought this would be pretty much the same just no cords. Everyday I have a problem trying to get the thing to work.
Summary: First try at a wireless mouse. I will not buy another. This one when it reponded to touch was difficult to move the curser and jerky. Half the time it just would not work. Thumbs all the way down on this one.
