Summary: (Jan 6th, 2008) Long story short, I used the MX1000 laser mouse (came out roughly Spring of 2005) and it worked extremely well with no hiccups, so I also decided to purchase the Logitech G7 wireless gaming mouse around January of 06. Nice design and good attempt but problems with the clicking mechanism that rendered the first three G7 mice inoperable after 40-60 days. Finally decided that 2000 DPI was great but ONLY IF IT WORKS CONSISTENTLY WITH NO HICCUPS. Decided to try out the MX Revolution as well, and so far, after almost thirteen months, it is working fine.
The 2.4 GHz wavelength of the MX Revolution wireless mouse reports laser position at about 570 Hz (times per second)(and it is not Bluetooth compatible). This means that if the software driver is written correctly (more on that in a minute) then the mouse has absolutely no detectable lag at its 800 DPI (dots per inch) resolution (yes, you can almost notice the difference, even compared to the already nice Logitech MX 1000 laser mouse). During the past several releases of the Setpoint drivers it seemed that there were some small flaws with the dual mode scroll wheel but it appears that the Setpoint 4.24 drivers have mostly ironed out this issue (notice, I said 'mostly'). Again, mechanistically, the mouse is holding up fine. Not surprisingly, if you do not install the Setpoint package, Windows XP will recognize the mouse just fine and you will experience no lag problems at all but you will not have full use of the fancy features like the dual mode scroll wheel or search button. These lag problems are also not as noticeable under Windows Vista and there are no problems with Ubuntu, Debian or Fedora.
The feet of the mouse are made of PTFE (simply the acronym for Teflon). What this means for the average Joe, is that this mouse feels like greased butter on most surfaces (no difference over the G7 but fairly big ergonomic difference over the MX 1000). The sides of the mouse are also rubberized and feel great with no loss of grip after hours of single session use. And unless you have tiny tiny hands you will enjoy the feel of this mouse. The mouse also weighs about 1.2 pounds which sounds heavy but believe me after fooling with all the problems of the G7 Wireless Laser gaming mouse, this rocks. With the teflon feet and nice weight, this mouse can slide even faster than George Nukcleare Strategery Bush can get us into another futile war, and that is fast!
The MX Revolution also possesses a great scroll wheel that can be set up in multiple modes with the Setpoint 4.24 software. Needless to say, that if you take the time to set up the button mapping with the software, then you can use this mouse to do heavy duty office work all day long and then game on it all night.

Summary - This mouse kicks butt and the Setpoint 4.24 driver package has solved any remaining problems for me with the dual scroll wheel. Overall, a nice package and excellent choice for only $40 on pricegrabber.

Summary: I've had a number of mice, and I haven't ever used one that I've been nearly as happy with as this one. I upgraded from the MX1000, for no good reason, really, but I'm glad that I did. The movement on this mouse seems more natural to me, and I like the variety of buttons. The fast-scrolling feature is pretty interesting as well, once you get used to it. I use it all the time on websites now.

If you're still using a wired mouse (or a wireless one you aren't happy with), I'd definitely recommend getting this. If you have something like an MX1000, I'd only recommned upgrading if you're very mouse sensitive.

Summary: great deal! haven't had any wireless issues and I love how smooth the mouse moves! Although it has less buttons than my old mx 740 but I still think it rocks! hope to use it with games soon, but have mostly been using it for business. wish i could customize that the search opens in a tab instead of a new window but im sure they will figure that out in a future version of setpoint!

One of the best mice I have had yet! just wish there was a place to put the usb receiver when it is not in use... so worried i will lose it :-P
