Summary: I was a bit hesitant to order this mouse in the first place, as every Microsoft mouse I have ever used has felt cheap and just hadnt performed as well as say a Logitech. But, I figured I might as well try it, and if I dont like it Ill just return it. Once I receieved it I was initially pleasently surprised. It didnt feel quite as cheap as I was expecting. It was still extremely light so it didnt have that going for it.
Summary: I've rarely had bad experiences with Microsoft mice or keyboards. Usually they tend to have above average design and put thought into the product. They evidently didn't hire the "good" designer to work on this product however as this mouse has 2 glaring faults. #1: The shallow height and shape of the mouse is such that it offers no support for your hand whatsoever. This causes hand strain and inconsistent hand placement as you use it.
Summary: I have diabetic vision problems and thought the Laser 6000's capacity to magnify small areas of the screen would be useful for maps, data sheets, etc. I've decided to return it and get a larger monitor instead. This mouse moves eccentricly and you move over the page or screen in fits and starts. Once you turn the magnifying function on, it can be quite difficult to turn it back off. In one case I had to reboot.
