Logitech M310 Wireless Mouse

I was concerned with ergonomics mostly and contemplated a lot before I found what I was looking for. With so many mice available there are the good and bad reviews but let the bad reviews not change your mind because mice, especially ergonomic concerns are all very subjective. This is what I failed to understand initially and that's why it took me much time to realize that. Since every mouse would be different to everybody, you shouldn't base your buying decision solely on that unless you start seeing some kind of a pattern with bad reviews which could mean defect in product that majority has found about. I had to chose between M305 and this mouse because it is "palm grip" type and bigger than M305. I picked M310 and now my hand can rest on it without being tense which isn't the case with my Microsoft Mouse 3000 "claw grip" mouse because I can't rest my palm easily on it and after long period of using it, I start feeling a bit of pain in my palm and hand. I now put my Microsoft Mouse 3000 aside and use only M310 with my laptop because not only does it offer good ergonomics, it also has mini-USB unified connector that goes into your USB port and stays there forever which is very convenient. Compared to USB transceiver of my Microsoft Mouse 3000, this one is a lot smaller, it's hardly noticeable and nothing will hit it accidentally even if you decided to dance with your laptop in crowded place. This mouse came with disposable battery but since I have only used this mouse one month only averaging 4-5 hours, I cannot tell yet how much battery lasts but given the popularity of low self-discharge durable batteries today, you can forget about worrying because after all, it's only one battery that mouse uses and you can buy a pack of 4 batteries for around $10 of either eneloop or Amazon Basics. I have both brands and they are great. I have no doubt that 2000mAh eneloop can last you 1 year with average use on M310 because you can turn off this mouse when you don't plan using it for some time. There is a green small LED in the middle that turns on for a few short seconds after you either turn you mouse or bring it out of standby state. In terms of functionality, it only has 3 buttons which suffices my browsing and office needs (I would appreciate 2 more buttons for back and forth surfing though) but if you do more than just browsing internet and office work, you will be missing at least 2 buttons more. I don't remember myself installing drivers and utility that came on CD with this mouse, but rather just plugging in and Windows 7 installing required drivers automatically. If you are gamer, there is one thing I am confident about - there is no utility that would allow you to record macro commands for expanded functionality in video games compared to Razer mice that have this. Actually in obsessive search for best mouse ergonomics-wise, I have bought Razer DeathAdder which was expensive and unnecessary for the purpose I bought M310 for. The wheel on M310 is what I needed because it doesn't just glide freely but has so to say "tiny stoppers" which sound clicky bettering your navigation and allowing you to break with accuracy after scrolling to certain positions. The range of this mouse is way better than of Microsoft Mouse 3000 which was like 1.5 meters max from transceiver and I had to be next to my laptop to use it. With Logitech M310 the range is now enough for me to stand at the room's door and controlling laptop at the end of room which I am sure is not the farthest it can do. There is one thing I liked the least which is high sensitivity of left and right buttons because do to me resting my hand on mouse, fingers tend to add weight on buttons resulting in accidental clicks. My experience is subjective however so keep that in mind so what I might have not liked, you wouldn't deem inconvenient. To conclude, I am very satisfied with my Logitech M310! It's has small transceiver, a good wireless range, it is conservative in energy because it can be turned off and automatically enter standby state when idle, it offers smooth scrolling and tracking, it has parking slot for its small transceiver covered by retractable cover which helps mobility. If you are mobile kind of person, working on your laptop doing office work or plain web surfing then you won't go wrong with M310.
