Microsoft FA1-00002S Black&Silver 4 Buttons Tilt Wheel USB or PS/2 Wired Optical Comfort Mouse - OEM

This mouse surprised me.

As alot of posts have metioned the scrool weeh rotates smoothly with no notches.

it is a nice mouse with a smooth scroll wheel.

middle button is somewhat hard to click.

I use this in Linux, so I need the middle button press action to paste like 100 times a day.

Almost always work.

Almost always work. Good Quality discs, I have never had a problem. Cheap

None

Nice sensitivity, four way scrolling, comfortable, work for left handed people, but that won't come in handy for me

Smooth scroll wheel sucks for gaming, and drop down menus ; Middle click slightly harder than average, if only due the fact the wheel will just barely scroll up or down when you press it, cancelling out your middle click causing nothing to happen

Very smooth! Great tracking. It picks up perfectly on everything I've tried it on. Works great for video games and you don't do the "ballerina" (Mouse goes to the top corner, and you spin)

Scroll Wheel is smooth (doesn't click when you spin it, so if you try to scroll a certain ammount, its somewhat difficult to get it exact
