Pros: Its a wonderful value. It fits well in the hand and has a good color scheme. Laser is better than RF. I'm using it with a distance of 3-4 feet and it works well.

Cons: Slightly small compared to my past mouse - I'm sure I'll get used to it. The mouse wheel feels a little cheap - not a smooth scroll click.

Other Thoughts: It took about 15 minutes for it to cycle through the various 2.4Ghz channels. It was interfering with my wireless G router. But after 15 minutes the problems stopped and everything is good to go.

Pros: Battery usage is limited and ultimately extended by inactivity shutting mouse down. Mouse works flawlessly. Good signal to mouse (perimeter is about 3-4 feet for me.

Cons: None

Other Thoughts: N/A

Pros: Excellent mouse for use with my Macbook running both OSX Snow Leopard and Windows XP via bootcamp. Worked right out of the box.

Cons: None.

Pros: The mouse is nice and feels good in the palm but something was grindy in the feel of the wheel operation. It does everything that it's supposed to but I decided to contact Newegg for an RMA to get a refund fearing the same problems with a replacement and when I did they told me to just keep it and they refunded my PayPal account the full transaction amount immediately. WHO ELSE BUT NEWEGG DOES THIS NOWADAYS??? That's why I buy so much from these guys... they're a GREAT COMPANY!!! 5-stars for Newegg.com

Cons: none

Pros: Plug in and it works on both Mac and Windows.

Cons: Logitech software does not recognize it on OS X, but since logitech does not care about the OS X platform to write good drivers for it, this is not a suprize.

Other Thoughts: Mouse is on the small size, so consider that if you have large hands and prefer meaty mice. The scrolling wheel just feels a little bit weird, but I can't put my finger on why.

Pros: worked right out of the box in vista, cheap (was on sale for $20 with free ship)

Cons: none

Pros: cheap, wireless laser mouse with decent range. I had a Microsoft wireless notebook mouse, that was a similar price, but the range was about 2 - 3 feet.

Cons: there is a noticeable lag when you stop using it for a while. But I think you can turn that off? I believe its a setting where when it is idle, it goes into some sort of power saving mode, to preserve battery life. so when you move it again, it has to resume. Not good for games, but not too bad if its just for web browsing.

Other Thoughts: it doesn't drain batteries that rapidly, still on first set.

Pros: relative long battery life.
laser precision.

Cons: lack of choice in left scroll click setting.
heavier than expected.
stutter and hang.
wheel middle click becomes left scroll click many time.

Other Thoughts: i have several logitech mice in past year got left click button issue which is extremely annoying, it keeps double click whenever just use one click. the quality of logitech mouse product is significantly lowered recently.

Pros: Nice mouse. Like the feature of the on/off switch. Works great with Windows and Mac OS X 10.4.11.

Cons: The only downfall I found for a lot of the mice out there is that they don't work with USB to PS/2 converters anymore. I've tried with a few converters that came with my other mice and they don't work. They got rid of the conversion part in the mice.

Other Thoughts: The mouse is really smooth in both Windows and Mac OS X. Macs picked it up without installing any drivers.

Pros: I put in the batteries, plugged in the receiver and it worked.

Cons: none so far
