The listing, Microsoft wireless notebook optical mouse 3000 has ended.
I've had this mouse for a couple of months and am very satisfied with it. There was no software installation. I simply plugged the wireless receiver into an available USB port, put a "AA" size battery in the mouse, and turned on the computer. The mouse started working just as Windows Vista finished loading.
I don't know how long the "AA" battery will last yet. I've had the mouse for a couple of months & the battery was still working. However, I'm using my laptop mainly as a desktop, used many hours each day, and the original battery is still going strong. To insert the battery, press the silver button directly below the "Microsoft" logo and the top pops off (the release button is designed to look decorative). At that point, one will immediately see the battery holder.
All in all, I think anyone would be satisfied with this mouse.
Highly recommended for laptops. Even though it has a "connect" button, never had to use it. Just plug and play installation. No need to download/install drivers. Used it with Win 2000, WinXP & Vista.
Pros ::
* Solid responsive mouse
* Soft buttons
* Cordless so no tangled wires around you
* Optical so can be used on ( just about ) any surface
* Small USB receiver
* * Used it, without any issues, with my wireless internet connection
* Easy to replace batteries
* Single AA battery
Cons ::
* Might be small for a person with large hands &/or long fingers
* NO carrying case. Even though the adapter fits *in* the mouse. It could help to have a carrying case as well.
* Not aware of any way to program the "buttons" ( for "left handed" persons )
