Title: a mouse that has achieved PERFECTION!
Review: In the past I have had Kensington roller ball mice, several other logitech mice including the old version of this one. This is by far the best roller ball mouse I have ever owned! The older version of it was not as good. They made some adjustments and now I would say it is absolutely perfect - and I am VERY picky about my mice!I bought the Logitech Trackman Marble Mouse and had to return it because it is cheap and hurt my wrist.I have now found the mouse I will use for the rest of my days, or it's days whichever comes first!
