Pros: Easy set up on Windows 7 64 bit.
Has an on/off switch and nano USB holder built into the bottom.
Works on USB 2.0 and 3.0
Battery life is pretty good.
Range is good: at 10-12 feet away it's very responsive still.
Buttons and center scroll wheel are solid and accurate.
The blue track feature is great, I can use it on just about any surface, anywhere.
Small footprint and light weight unit.

Cons: The only con that I have found is that the plastic/rubber sides tend to come loose over time.

Other Thoughts: This is a nice, compact, well working wireless blue track mouse that is easy to install and use just about anywhere, I have 2 of them, one for my laptop and one for my desktop. Both are Windows 7 64 bit, and this little mouse works just fine on both.

Pros: Smaller than normal size, perfect for my mother's small hands. Works on all surfaces.

Cons: The left click wore out after 4 months of normal use. I have to get finger angle/pressure/placement just right to even maybe use the left click now. I used the Microsoft software to change the R-click button to act as L-Click for now. Will be RMA'ing.

Pros: Bought this for my girlfriend to go with a laptop I got her for Christmas. It works great on any surface and it's somewhat small size fits her hand nicely.

Cons: None so far

Other Thoughts: We have since broken up, but I can't blame the mouse or newegg for that. If I could I would give it 3 extra eggs!!

Pros: This is my Favorite mouse I have been using this type of mouse for 2 years. They were E Blast with a code so I purchased 2 more and also sent to a couple of friends, they are pleased also.

Cons: battery life could be somewhat better, My fault I forget to turn it off there is a on-off switch on the bottom of the mouse

Pros: As promised, works well on many surfaces. Fairly comfortable. Came with Duracell battery.

Cons: The 3 button description is somewhat misleading. I thought it meant it came with a thumb button. It doesn't. Should have looked at the photos closer. The 3rd button must be the click option on the mouse wheel.

Pros: Small, fits smaller hands great. All of the buttons are relatively easy to reach.

Cons: Switch is slightly louder than other Microsoft optical mouses. The higher priced units have quieter operation.

Other Thoughts: Works as intended and doesn't require you to sync it with the receiver. AUTOMATIC!

Pros: I've had a lot of mouses in my life and I've never seen one to handle odd environments as this one does. It works as I would logically expect it too off of my loveSac and other surfaces. Other mouses that have claimed to be great on various surfaces didn't hold up as well as this one did.

Cons: It's smaller than normal. I wish it was standard sized.
