Pros: I picked up several of these when they were on sale for under $10. I use them when I need to throw a mouse on some system. I find them reasonably ergonomic, and haven't seen the problems others have reported. Tracking is good. Good value for the price.

Cons: None that I've encountered. There are more full featured mice, but they're at a different price point.

Pros: Travels well. Small enough to pack but large enough to use.

Cons: None

Other Thoughts: Great alternative to touch pads.

Pros: Compact, attractive, accurate, battery efficient.

Cons: Never thought about how loud a mouse could be with its button clicks until I bought this one. Bought it so I'd have a mouse to use with my laptop at the library, went to use it in the quiet study room and I was embarrassed to use it!

Pros: I use the mouse everyday on my desktop and though it is slightly smaller than my old Logitech M310 which I used for years it is still good for me.I like that it uses only 1 AA battery and should last a long time.The dongle fits nicely into the bottom of the mouse in case I want to travel with it.Well made.

Cons: My one complaint is the scroll wheel.It is too easy to push it down and it goes into that other mode where you have to move the whole mouse up and down to scroll.You have to reclick the wheel to stop it.Thank you to anybody who has an answer.

Other Thoughts: Good shipping and no damage.

Pros: Looks nice.
The red matches my LED desk lamp
Microsoft name was reassuring.

Cons: Worked for a week. Then the left button now acts the same as pushing the wheel.
I click on tabs and it closes them.
I click on a link and it opens in a new tab.
Click on anywhere in a page and i get the scroll effect.
Wasted $10

Other Thoughts: Yes I tried it on other computers and different operating systems, same effect!
Its the mouse that has failed!!

Pros: Comfortable feeling and sharp looks.
And it runs on my copy of Windows 10 Professional 64bit SP1 fine though the "Technical Data Sheet" doesn't specify Windows 10. It does everything I wanted from this mouse. Plus it can be used, seemingly on any surface.

Cons: I gave the unit 3 stars because of some irritating things going on.

• First and foremost is the fact that I can see that it’s going to be a bear keeping track of the dongle. My old Logitech mouse, before I decided to run it over with my truck, had a caddy built right into the mouse, making it easy to keep track of the dongle. I've taken an old pill bottle that I intend to store it in.
• The mouse is almost too sensitive. Every mouse movement seems to exaggerate what you do, making it hard to control.
• Knowing full well that it’s almost too small. Of course, the small size is almost a given, and to some extent a given, but I was taken aback to the small size compared to what my old Logitech mouse was.

Other Thoughts: • Please note that I rated this mouse one star earlier. I talked to NewEgg earlier, requesting that they delete my earlier statement, so that I may reevaluate the product using the facts that have recently changed. Though I’m not 100% “liking” this mouse, it does the trick, plus the price of $10 on sale was particularly nice.

Please ignore my earlier review where I’d given it a 1-star rating.

Pros: Small, wireless, cheap, long battery life, comfortable to hold.

Cons: Has a defect: If you let your computer go into Standby {as in closing a laptop lid}, when you get it going again, the scroll a web page in Internet Explorer crawls. It you remove and re-insert the dongle, it goes back working. Have tried this across several computer with all three of this model, all exhibit the same. Get a Microsoft 4000 series, it does not have this issue. I will not get another Microsoft 3500, not even if FREE.

Pros: Power switch, cordless, portable, good sale price.

Cons: A little small for every day desktop use, but that's obvious before you buy.

Pros: Mouse will work on any surface even your sheets. The only problem I had was it's so sensitive that I end up licking the mouse button when I don't want to. I have Parkinson's though. The only downside is it won't pair with any Microsoft's wireless keyboards.

Cons: Won't work with any of Microsoft's wireless keyboards on same dongle.

Other Thoughts: Like I said earlier it won't work with any Microsoft Keyboard with micro dongle. If your looking for that your best bet is Logitech.
