Summary: The Logitech Performance MX has a nice, comfortable feel. It is very responsive and the battery lasts all day for me, which is roughly 12 hours of continuous use - I plug it in to charge every night. For me it has worked on wood, glass, fabric, and laminated desktops. The Logitech® Unifying receiver was plugged in and the mouse connected right away with no problems using Windows 7. Read more...

"The so-called Darkfield laser technology may sound a bit pseudo-scientific, but in reality the tracking is still done by your average, garden variety lasers - two of them, to be exact, working together. On glass these lasers work using dark field microscopy (hence the name) to track imperfections (scratches and cracks), rather than reading the surface proper."

I have to admit that I rarely need to use a mouse on a glass table, but it has happened. I also admit that there is a mousepad that comes with me whenever I venture out into the world with my laptop. Logitech has felt my pain and has come up with Darkfield laser technology to solve what ails me. Most likely a response to Microsoft's Bluetrack mice, Logitech's new Performance Mouse MX and Anywhere Mouse MX work on pretty much any surface, including glass. It is also nice to see that you can charge the mouse while using it, eliminating the need to bring a spare set of batteries. I'm skeptical that Darkfield works as well as Logitech claims. Anyone willing to bite the bullet and see if these work as advertised?
