Logitech M325 910-002965 Black Topography Tilt Wheel USB RF Wireless Optical Mouse

Pros: It's small, uses a nice long lasting AA battery, and is pretty accurate and reliable. It doesn't feel very cheap, either.

Cons: The scrolling is a bit too sensitive, and the little feet get dirty really easily.

Other Thoughts: I have pretty big hands, but this little guy is just fine in my palm. My fingers hang over the buttons by about a knuckle, but they don't touch the table.

Pros: Smart Sleep mode turns mouse off when no signal from PC is detected; one AA battery; micro comfortable to use; very smooth scrolling; tilt wheel.

Cons: None yet!

Other Thoughts: Logitech mice last a long time, are not battery hogs. Ergonomic contoured shape, they're even pretty with many colors and painted-on designs available, Unified micro receiver interfaces with other Logitech devices and stows in the mouse for storage.

Pros: Improvement over the old EX100 combo. Mouse is quiet and I really like the smooth scrolling. I alos like the idea of using just one battery.

Cons: None

Pros: This Mouse Has a range of at least 25-30 feet... haven't had it in a big enough open area to test a longer range yet but will eventually, accurate, lots of settings in its software, fast wakeup from standby (instantaneous so far... can't tell if it is or isn't in standby), it has worked on almost all surfaces that i have used it on (including some glass, but its tracking was a little off on it), the lack of the annoying red laser light, the tilt wheel (easier to use then having buttons on the side of the mouse) and the Micro-precise Scrolling (more details in cons)

Cons: Micro-precise Scrolling...As much as i like it now that i got it figured out, it is a annoyance to use if you don't change the settings. the performance is much nicer if you set it to scroll size 1 line instead of 3. its also easier to hit links with the middle button when it is set to 1. being micro precise it is also super sensitive so the smooth scroll app is greatly appreciated to help with the slowing of the movements

Other Thoughts: Overall its a good mouse now if you have it set up with the software apps and the Scroll wheel's lines per size at 1 line. I had to take 1 egg just for the not defaulting to settings that made scrolling easier but it was easy enough to fix anyway
