Pros: Solid everyday mouse at a reasonable price. Decent quality for the price. Large, ergonomic shape fills your hand and is comfortable to use for long periods. Includes PS/2 adapter just in case you need one.
Cons: Cheap feeling plastic. Two side buttons are loose, but seem to function OK. Scroll wheel feels "clunky" when new but should get better with use.
Pros: Good tracking on almost any surface. Non stick feet are very smooth. Side buttons are not as big as I thought they would be. I was worried that the side buttons would be ridiculously big like the Microsoft D58-00032 and therefore hamper web browsing but I have yet to be taken back a page while using this mouse.
Cons: Mine came with a broken mouse wheel. I just opened up the mouse and super glued the part that was broken. I guess that's the cost of buying something OEM. The buttons ( All of them ) need to be pushed a little harder but that's not really a big con since the force needed is so trivial.
Summary: After numerous dissapointments with keyboards and mice about 9 years ago I made the decision to only purchase microsoft. Have never regretted it. Would have preferred a bit more weight behind it, but all in all a very satisfying mouse.
Summary: I bought this for my wife, who likes to switch hands occasionally. Her old mouse is an Intellimouse version 1.1 and can be used either right or left handed. I thought this version 3.0 would be the same but you need to take a close look at the pictures to discover that it isn't. Anyway, it's a good mouse so I kept it for myself.
Summary: I've used Microsoft Mice on and off for about 13 years. I've always found them to be very good quality and very accurate for online gaming. This mouse is no different. It's got that typical top quality microsoft feel to it. The spare buttons work a browsers back/foward buttons. I presume but haven't tested that they can be used as alternate weapon buttons in games like Counter-Strike and Quake 3. Easy to presume because with older mice, they did.
Summary: it does seems to be a good mouse, its really smooth and just glides along with not much resistance and its sent with all the relevant information and driver disc. the packaging isn't over the top and protects the mouse well. the only real gripe i have is that the buttons feel cheap and the scrolling wheel is very clunky and doesn't feel that good. also the picture shown has a black mouse which is what i thought i had ordered but its actually a dark silver-ish colour.
