Summary: The scroll wheel isn't great, but it does work. The battery covers aren't very secure; I had to tape both of them to keep them from falling off. It isn't a big deal, but these are clearly not the top of the line. They are very inexpensive, though.
Cons: I bought 2. The scroll wheels are not very responsive and the battery covers fall off
Summary: Got what I paid for, no more, no less. I would not recommend using this for your desktop or gaming mouse; it's honestly a travelers mouse. I kept forgetting to turn it off when I was done with it for the first week or so since there isn't an indicator. Eventually you start to remember. Sooner or later I'll get something of better quality. It's a gaming laptop that I use it for; this doesn't even remotely fit the niche of a gaming mouse.
Pros: I use this for my laptop mouse. It's half the size of my PC mouse and the micro receiver can stay in the USB slot when I put the laptop in its bag. Basically good for travel. Battery life is great for sure. Inexpensive.
Cons: Bad form, not comfortable at all. Maybe too light for my liking. I like something with some mass to it. It actually feels cheap unlike the other Logitech mice I have used. Can't tell if it's actually on or not. Only an issue when you're trying to troubleshoot the mouse, which I had to do within 2 weeks of owning it. Randomly had it lose connectivity on me, as with the point above I was at a loss because I didn't know if the thing was even on. I eventually had to downl...
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 needed a new mouse & Logitech has beem my choice for 15 years. Based on the reviews I was ready to buy the M185, but when I saw it at Wal-Mart I found out it was to small & did not fit my hand. I did buy the larger size M510 it fits very comforitly and works very well. If you are a adult look at the M510 (it may cost more but you need to be happy with what you get).
