Summary: It was buggy from the start and then it broke. Bad quality, don't buy.
Pros: Was fine while it lasted.
Cons: My pc would have trouble recognizing the device occasionally. The battery meter would flicker "low battery" warning from the start, even when this was not the case with prepackaged battery that was new. Finally it just stopped working. Tried brand new Duracell batteries to no avail as well.
Summary: I have actually purchased two of these as I left my first one purchased on a airline. I thought I could do without it as I own about 10 wireless mice. That lasted about a week and I had to purchase another. This mouse is absolutely the best mouse I have had in my 30 years of computing.
Summary: This was the cheapest mouse I could find in the brick-&-mortar store. They wanted to charge another $10 for a full size, which probably cost the manufacturer another 2 cents. Good reviews on Newegg. Maybe I'll keep using it and maybe my hand won't spasm.
Pros: Kept scrolling 40 feet from the receiver, without walls. I would have tried it with intervening walls, but then I wouldn't have been able to see whether the monitor was still scrolling (or not). Windows installed drivers in a minute; I didn't install any other software.
Cons: This mouse is so small, I think my hand is going to start spasming if I keep using it for too many more days. I had to readjust all my mouse settings when I got rid of the wired mouse.
Pros: Small, fits in my pocket easily and even my tiny hand. It's a quiet click and no laser for noobs to shine in people's eyes. This mouse has the smoothest scrolling I've ever seen. After I downloaded and installed the SetPoint and ScrollApp from the Logitech web site, I have the icon in the taskbar...
Summary: I was looking for a very small wireless mouse. I have weak hands due to a severe disability, so it was important to me that the buttons be easy to press. They are. The only minor feature I wish it had was a way to scroll left and right. Overall, it's a good value and met my expectations.
Summary: I was looking for a good quality mouse that is average sized. It obviously says mini mouse but I guess I just didn't see that. I had a good working mouse before I bought this. I just wanted to get a new one since the old one is sort of wearing out but...
