User Review: The Enter key on the 10-key numerical pad gets stuck if you press it on the upper part, which I often do while I'm typing numerical data.  That's really frustrating.
Installing everything was a slight pain, mainly because I couldn't use the mouse until the logitech drivers were installed.  Thankfully I had an old mouse laying around and used that to finish up the install.
The mouse moves REALLY fast.  I'm not used to moving the mouse just a small distance and having the cursor jump across the screen.  I can't slow it down, either.  Clicking on Control Panel -> Mouse -> Motion will bring me to the place where you can speed up or slow down the mouse.  However, the speed is set to the slowest setting, and I can't adjust it.  If I move the slider bar to the right, it just jumps back to the left.
Moving the mouse slowly on my desk (a dark wood, standard computer desk) makes the cursor jump around in the wrong direction at times.  Most notably, when I move the mouse slowly to the right, the cursor will jump left and then right jaggedly.
My biggest problem is that I can't fix the motion speed.  I've tried uninstalling and reinstalling the drivers with no luck.  It's really handy to have a cordless keyboard and mouse, but the mouse is so difficult to use that I find myself relying on the keyboard more often than not.
The nicest thing about the keyboard is that it has it's own scroll wheel built into it, so you don't have to reach over to the mouse to scroll the active document...
