Summary: As many of the other reviews have noted, this is a great mouse because of its portability and its ease of use. There is really no way to screw up installation. The size is perfect for traveling. That being said, I would not recommend this as your everyday mouse (especially if you're spending more than 5 hours a day at your computer). I have had this mouse for a few months and by the end of the day, I notice my hand cramping and wrist hurting from the smaller size.
Summary: This mouse was alright when I first got it about two months ago, but the right click is already nearly non-functional. There is not much else to say. I guess I should have gotten a more expensive one.
Summary: This is the third Logitech wireless mouse I've had, and the second optical. The two previous ones lasted less than a year but I am addicted to the size and ease of function, so I'm staying with them. The little USB receiver nub couldn't be any smaller or unobtrusive and works well. There's a little storage slot inside, under the mouse cover. for it when you travel so you don't lose it. Mouse size fit and finish are good and it is a perfect size for my hand.
Summary: It has all of the features that I want it's just that they don't work. It's a total crapshoot whether upon clicking the mouse it will register 0, 1, 2, or more clicks. My sanity is already in question. I don't need this thing pushing me over the edge. Bottom line, nice try, but it's a FAIL.
Summary: This was my first mouse I've owned since I switched to Linux from Mac, and I just hate it! It's nice to have a compact mouse I can take anywhere, it's convinient, yes. But it's got a huge clicking issue. Half the times I try to click or drag something, it decides to double click instead. I'm really fed up with this thing.
Summary: I am a moderately heavy user, not a gamer though. I was initially pleased with this mouse and am happy to report that the battery life was relatively good as it outlasted the left button which started giving a double click instead of a single click. I didn't expect it to last the 10 years that my old Microsoft mouse did but a little disappointed to chuck it in the bin today. Definitely not as good as Logitech stuff I've owned before.
Summary: The M184 mouse was very good to use but the very small nano receiver can push the USB port into the laptop if it is accidentally knocked. It would be stronger if the nano receiver had a plastic lip to stop it being pushed to far into the USB port.
