"Just got this in the mail and it worked right out of the box once the batteries were installed, the adapter plugged into the laptop and the switch turned on. My Thinkpad automatically found and set up a driver for it in about a minute or so. I like the solid feel and click sound and overall weight of the mouse (with the batteries, it is heavier than a regular usb mouse, of course, but the weight gives it a certain solidness which I like.) I didn't find the 'Mouse Suite' software useful - downloaded it from the Support/mice site, but maybe others can find something of use there. From the day I ordered the mouse, to the day it reached me was about 7 days - excluding a wknd, abt 5 business days. Not bad, and UPS did a good job of delivering it right to my door."
