Title: The Best (with one caveat)
Review: This is really the best input device out there, for so many reasons. Believe the hype.There is one unavoidable flaw, however; the scroll wheel WILL stop working eventually. I've now had my third one fail in as many years. Fortunately, Kensington has replaced it each time. My fourth Expert Mouse is in the mail now. Kudos to Kensington for honoring their warranty so faithfully, but I have to wonder why they don't fix the underlying problem.Anyway, this is a great product which has taken me well off the path to carpal tunnel syndrome. I recommend switching hands regularly. I've written an AutoIt script (surprisingly easy to do) which quickly toggles the buttons between right and left handed configurations, and assigned the top two buttons (clicked together) to launch the script. This way, I can switch hands and have the buttons mirrored with a single click. Becoming ambidextrous with the Expert Mouse shouldn't take too long to master and is well worth the effort.
Is the review positive or negative?
