Summary: Because Microsoft lists it as Vista compatible you would think they tested it on their own software. I continue to use the mouse even with the scrolling problems because of the it's comfort level.
Pros: Very comfortable after getting used to it. Has relieved the wrist pain I was having because of working on the computer for long periods of time.
Cons: Scrolling does not work very well in some programs including Microsoft programs like Access 2007 and Windows Photo Gallery. To make it scroll you need to spin the wheel very fast. It works normally in other programs like Word and Excel. Changing the mouse setting and Updating the mouse drivers an...
Summary: I've built many computers for clients. I've included MS mice exclusively. I have gone back to the optical mice, since those are reliable for the long haul.
Pros: Very quick and precise.
Cons: Side buttons not in good position for me. Maybe fine for others. I could live with that, if it were not for the main button (left click) failing on two units [that I used] within three to six months. This mouse is not built for heavy use.
Summary: The flaws I pointed out have been experienced by both myself (with very large hands) and my girlfriend (who has fairly small hands). This is not just a size issue! I have to imagine that the same problem would effect lefties, so I'm honestly shocked that this mouse received so many good reviews.
Pros: Very smooth tracking, good action on the two main buttons, nice scroll wheel.
Cons: Insanely bad design! Since the mouse is designed to be ambidextrous, there is a button on either side of the mouse where a thumb would be for either a lefty or a righty. Great idea! Problem is, where the thumb button is located for lefties is where my ring and pinkie fingers go. Even bigger probl...
Summary: Spend a little more and get another brand...
Pros: Good price point, excellent tracking.
Cons: Shoddy quality, uncomfortable... Left click stopped working 2 months after purchase. Laser logo on the bottom is not smooth, has sharp edges that make it uncomfortable to use for extended periods of time.
