Microsoft Comfort Mouse 6000

Pros: Looks decent, has grippy-sides, and glides easily across my mouse pad and plastic table.

Cons: Locked to 125Hz polling rate.

Other Thoughts: I find it takes a normal amount of force to click the mouse, but to be fair, I'm coming from a Comfort Mouse 3000.

As for the polling rate, traditional means to change it from Windows don't work. The mouse works fine regardless though.

Pros: The precision of this mouse is great, they did an awesome job upgrading the tracking technology over the IntelliMouse Explorer series.

Cons: The buttons are just TOO STIFF. I bought this as a replacement for an aging IntelliMouse Explorer, partly because the physical shape was similar. Upon using this mouse, I found the buttons (especially the middle click and thumb buttons) to be too stiff to the point it hurts my wrist to use after even a short period of time. After using this mouse every day for work for 2 week, I had hoped that the buttons would have been "worn in", but this just isn't the case, they're as tough as the day the mouse came in the mail.

Other Thoughts: Not being able to comfortably use the button on a mouse named the "Comfort Mouse" almost feels like it is entirely misleading advertising, especially after how soft and smooth the buttons were to press on any mouse in the IntelliMouse Explorer series.

Pros: it's an inexpensive 5 button mouse that functions

Cons: cord is very cheap, forward and back buttons are placed too high to comfortably have quick access to them, middle mouse click has a noticeable delay when clicking it. (eg. opening links in tabs and closing tabs)

Other Thoughts: compared to my previous MS intellimouse 3 which this mouse replaced, it doesn't come close.
