Summary: I sit at a desk for hours, and use a mouse a lot, so having one that was comfortable is important, Microsoft seem to make mice that fit my hands better than logitech, and this one fits fine and just works...
Summary: Fantastic mouse. I now have one at every PC that I use. Buttons are exactly where you want them. As a warning to those looking to purchase the (often cheaper) Comfort Mouse 6000 for business - DON'T! Buy this one instead.
Summary: Probably the loudest mouse you will ever hear. When you click on it, its noisy...I have a brand new pc, the mouse installed the first time, but now have to reinstall it before use. There are better ones out there
Good ergonomics, but loud button clicks and maddening 1/3 second delay with middle button click

Summary: It feels great in the hand and has high resolution. But it's not perfect: 1. The main buttons click very loudly (causing a fellow train passenger to complain once) 2. Worst of all there is a 1/3 of a second delay between clicking the middle mouse button and the resulting action taking place.
Summary: First off, yes, there is a noticeable lag on the middle mouse button. About 0.1 to 0.2 seconds. It's a hardware problem with no fix. If you can't live with it, don't buy it. I had a second problem though.
Summary: I needed a replacement for an ageing microsoft intellimouse and as these now sell for silly money and I've never been a fan of wireless mice I went for one of these. I was sufficiently impressed that I bought another for work to replace the mouse I was using.
