Logitech M510 Wireless Mouse, Black

I've only had it for a couple days now, so I can't speak about this product extensively. But it's been great for the first couple uses. I'll go over a few notes about my use so far:1. It feels perfect in my hand. I was very worried about the size and feel going into it. With something like a mouse, it all comes down to personal preference. I went to Best Buy so I could find one that fit my hand well, but they didn't have any displays out to try. So I took a shot in the dark and bought this one off Amazon. I have small hands, but I'm a fully grown man, so I probably have pretty average hands for all users. It's big enough to use as a full size mouse but small enough to not be too large. The ergonomic place for your thumb is very comfortable. As an added note, I love the blue color. I decided to go with it instead of the plain black and I spent a little more but it looks great.2. Another thing I was worried about was losing the dongle. In a perfect world I would leave it attached to my laptop. But I bought the mouse to use at work and I use a different computer every day, so I knew I would drop it eventually without realizing it. However, I found out there is a place to store it in the battery compartment. GREAT feature that isn't even mentioned in the description.3. The buttons are solid yet easy to press. There is little resistance without having much opportunity to accidentally click or double click. I have not tried the two buttons next to the thumb space yet and probably won't put them to much use. They are out of the way enough that they don't cause a problem, yet are within easy reach for those who plan on using them.4. The set-up (or lack of it) is idiot-proof, as my father would say. You plug the dongle into a USB port and it's ready to go. There's no software to install unless you want to use the extra two buttons, and you can flawlessly switch between computers.Overall, I am incredibly happy with this purchase. I was trying to choose between this and the next step up, the slightly more expensive Logitech Marathon M705. If you are trying to make the same decision, don't think twice. Save a few bucks and get this one, which is also larger. (Note: I haven't ever used the M705 so I can't speak for that one. I'm just going off how much I like this one.) Very happy with my purchase!Edit: 6 months late, I still love this mouse. I use it 40 hours a week at work and have yet to change the batteries. It's also surprisingly sturdy. I have dropped it on stone tile at work multiple times, and it still looks and works like new. But even if it did break, I'd immediately buy another. It's still extremely comfortable, and a handful of co-workers who have used my computer have told me they really liked using the mouse. Highly Highly recommended.

I have had this mouse for years...not sure how long, at least 4-5 years, best I can remember. I was recently thinking how much I love this thing, and figured I should write a short recommendation.So, first of all, I have used this mouse for gaming, and it's great, but it does have only two side buttons to go with the wheel and normal left/ right mouse buttons. So if you want a mouse with umpteen programmable options, look at another mouse. But it is super accurate (far more accurate than any non wireless mouses I have used), and I have had not a single problem with it. It is the size of a normal business type mouse (minor edit, I'd say it is *slightly* larger than some business sized mouses...but it is a plus to me, since it is far more comfortable for me to use than most mouses...in any case, people with very small hands may find it a little large), which is a plus to me. I don't believe I have yet replaced the batteries even.I used this on my desktop for years with absolutely no issues, and I just started using it on my new laptop with absolutely no issues. I wish every piece of computer tech I have used over the last 30 odd years was as satisfactory and reliable as this mouse. Prior to this, I used a Logitech more gaming oriented mouse at home (sorry I don't have the model number at hand), and I loved that mouse, and it was slightly more programmable, but honestly not much more capable than this one...and it was not wireless. If this one bit the dust I would instantly buy another.The most most accurate and reliable mouse I have ever used. And cheap, too. Strongest recommendation.

If I could give this mouse 4-1/2 stars I would. But only because of the few snags I ran into when I first installed it. I already had a Logitech wireless keyboard with a unifying receiver, so I didn't plug in the one that came with the mouse. For a couple of minutes nothing happened on my desktop and the mouse was not working. Logitech really shouldn't tell you it's plug and go when it's not! I went to the kitchen for something and when I came back there was a window up with instructions for getting the mouse to work with the keyboard unifying receiver. I followed them and at the end of the process a window popped up telling me that the procedure had not worked for my keyboard [they gave me the correct model # for the keyboard] and my mouse [for which they gave me the WRONG model number]. I closed out the window and tested the mouse and it was working just fine except that it wouldn't scroll. No matter how often I turned the wheel forward or backward there was no scrolling going on at all. I then went into SetPoint settings and found that for middle button the task selected was --are you ready?Middle Button. That made little sense so I changed the task to Universal Scroll and now the scroll wheel is working fine. Oh, and somewherealong the line SetPoint has figured out that I have a model M510 mouse and corrected that error on the top of the SetPoint Settings window. How in the world that happened I have no idea and I'm not sure I want to know. LOLSince everything seems to be working fine, I'm quite happy with this mouse. I have not downloaded the software for the side to side scrolling yet so I can't speak to that. As I've never had the opportunity to use side to side scrolling I don't know what I'm missing and at this point I don't much care, so I probably won't be downloading the software any time soon.Update 3/28/16: I bought this mouse on amazon.com 12/18/14 for $27.22. Once I figured out how to get it working, it worked fine until a week ago. I'd attempt to move my cursor from one point to another and it wouldn't move. I had to move the mouse around in quick circles to get it to work again. It worked fine for a few minutes then it hung up again. Thinking it was the batteries, I tested them and they were almost completely full. I put the batteries back in and continued to use the mouse for a few days. But the glitching happened so often, it was driving me crazy, so I uninstalled the Logitech M510 and put in a wired Dell mouse that came with my computer. I'm very disappointed in this development as I've loved this mouse. It's ergonomic features work wonderfully well to not aggravate my carpal tunnel syndrome. Sadly, this mouse has now been retired. I'll keep it in the drawer where I keep old computer hardware that may or may not work after 6 months or so of lying idle. Don't smirk! We all have a collection of old computer hardware that we can't bear to throw out for one reason or another.Given how much I loved this mouse coupled with it's relatively short lifespan, I have to now give it two starts.
