Comfortable Mouse & Smooth Operation
Style: M705
I bought this Logitech M705 to replace an aging one with a touchy left click button, which was part of a wireless desktop keyboard and mouse package (MK700) that was purchased over a decade ago. So, replacing the old M705 with a new M705 was a no-brainer.
After receiving the new M705, I inserted the battery and expected the new mouse to connect to the old Logitech Unifying Receiver automatically. To my surprise, the mouse didn't work, so I plugged in the new USB receiver and the mouse worked, but not the old keyboard. Perplexed, I started looking at Amazon reviews and thankfully I ran across a review from Rudy which helped solve my problem quickly. Turns out I needed to go to logiwebconnect.com to get the new mouse to work with the old unifying receiver. Once I did, I had the new mouse working in a matter of minutes.
I saw a lot of negative reviews for the newer version of the M705, but the new mouse build quality is good, it's as comfortable as the old M705, and it works flawlessly for me. The buttons are responsive, the scroll wheel has detents, and there are no issues with random scrolling with the scroll button engaged. I used to work as a PC technician, and my experience is in most cases when there are issues with peripheral devices it ends up being the PC itself, and rarely the peripheral device.
Overall, this a great replacement for an aging mouse, wired or wireless, or if you are considering a new mouse. If the battery life matches the original M705, which I'm certain it will, expect to get many years of operation without replacing the batteries.

One of the Best
Style: M705
I've tried other names brands over the years, but always come back to LogiTech.
Logitech makes some of the best wireless mice. This recent purchase is my Third M705 mouse. The previous one lasted almost 10 years before it started acting a little quirky. It could have only needed a good cleaning, but for the price it is easier to get a new one.
I also recently bought a new computer, because my 9 year old Win 7 HP physically broke at the screen hinge. The well-designed Logitech M705 mouse lasted longer than my last two computers. LOL
I love the design and I'm so glad it hasn't changed over the years. The mouse is very comfortable to hold and the buttons and wheel feel like a normal part of my hand. The mouse also has (programmable) side buttons, which are thumb operated for Forward and Back for use in a browser. They can also be easily programmed for reverse operation (whichever seems more natural for the user). Or, they can be programmed for custom commands in programs, besides the standard Forward/Back in Web Browsers.
The description says the batteries last up to 3 years, and they literally do, with good quality (Duracell) AA batteries. The mouse also gives an on screen notification when the batteries finally get low.
The mouse uses a very small USB dongle (Receiver) to communicate between the mouse and computer. There is no need to Pair devices via Bluetooth. Simply plug in the USB Receiver and start using the mouse. It's truly Plug & Play.
It's fortunate that the receiver & mouse are Plug & Play, because the the printed instructions are all but useless. The are no visual diagrams. And the instructions are printed in multiple languages using micro-fine text that is almost illegible.
It's worth pointing out that the USB Receiver is hidden inside the battery compartment and is so small it is easily overlooked. It's a good design to prevent losing the receiver when using multiple computers, or taking from home to school/work. But it confused me at first, because I expected it to be a separate item in box, which I thought was missing.
Overall, I highly recommend this mouse. I've bought it before and I'll buy it again.
UPDATE: To MKay who is getting the 3 blank screens with images of multiple open programs. That is not a error with the Logitech mouse. On some versions of Logitech mice, there is a very small (almost unnoticeable) on the left side at the bottom. It is (by default setting) used to scroll through multiple open programs/windows when the taskbar is hidden. Microsoft Windows 11 (and probably earlier versions, too) has the feature of TaskView (a setting which can be turned off in Taskbar settings). The TaskView has a black & white icon on the Taskbar. It is a very annoying feature IMO! The small (programmable) button on the mouse is most likely activating the TaskView feature - which is exactly as the picture you provided. Don't get mad at LogiTech for an MS Windows feature. Simply turn off TaskView in Taskbar settings, or reprogram the button on the mouse to do something else - and Love your mouse again!

Everyone knows this is one of the absolute GOATS of Logitech Mice - get one before they're gone...
Style: M705
I've had many Logitech mice over the years I've really loved that were then discontinued. This is a long running mouse that pretty much ALL logitech users just love! And since it's long in the tooth, I'd recommend stocking up while you can. Here's some of the perks, but above all else, it feels so amazing!
1. It's a smallish, very light, simple mouse. I personally don't like the giant gaming mice. This has everything I need, including a scroll wheel you can click between smooth and ratcheted mode.
2. Uses 1 or 2 AA batteries - This gives it incredible battery life - many months at least. And when you do need to replace batteries, it's instant. I keep a pair in my backpack. So much more convenient than having to charge a rechargeable mouse, especially given rechargeable batteries slowly wear out.
3. Works like a dream on Macs with no drivers installed at all!
4. You can stash the wireless USB receiver dongle inside the mouse! Which is priceless.
Note that nowadays, I have an Apple Silicon Mac, I have to use a tiny adapter to plug the dongle into a USB-C port. But it's still tiny and convenient.
5. For me, Logitech still hasn't made anything better. I'd love to see a mouse almost like this with a USB-C receiver, but until then, it's as close as it gets to my perfect mouse. I have tons of these all over the place.

For the price, it's a very good wireless mouse. But it's not my MX Anywhere.
Style: M705
I have two first generation MX Anywhere Mice that have countless hours and probably thousands of "miles" on each of them. Didn't know what they were about until I'd owned the first one for a few months, which eventually led to my buying a second one. That second one was "refurbished" because it was purchased some time later (from Amazon), as by then the second generation had been released and I simply liked my first gen so much I wanted another. So why did I buy the M705 Marathon Mouse? Well, the MX I've used the most over the years turned out to be the refurbished one. Why? Luck of the draw? Don't really know, but because of the constant, daily use it began giving me problems with double clicking on the left button and occasionally on the right button. That's a lot of use! I looked at buying the latest MX Anywhere mouse, but didn't like the prices and couldn't be sure if they were as well made as my originals. So, I ordered the Marathon, which appeared to be a less expensive version of the MX. Well, unfortunately it's not. Compared to most other mice, the Marathon is fine; typical good Logitech ergonomics, tracking and getting the job done. But, park it next to my MXs and use them one after the other and you "feel" the difference. As old as my MXs are, they still feel more precise, tighter and more responsive than the Marathon. They also are a better fit for my hand; the Marathon is a larger mouse which for where I use it means it doesn't "fit" my work area as well. Also, Logitech claims you can "customize" the Marathon using their software, but it was a lot of work to actually find "that" software for the Marathon and once I did it simply did not work as well as the software/MX Anywhere combo I've used for so long. What the Marathon has going for it is it's price, it's still an RF (radio frequency) and not a Bluetooth mouse (I hate Bluetooth mice, totally different response curve), and it is "Logitech." So what does all of this mean? Well, I put the Marathon to work (yeah, no more unwanted double clicking!) and parked the refurbished MX. I then checked on Mouser Electronics, found the correct replacement switches for my MX ($0.80 each), ordered them, and upon arrival I replaced the old switches. It was an easy swap on the little MX circuit board (it did require some extensive tear-down), with the result of: My old MX is back in service! And what's to become of my Marathon? Well, it's a good mouse, so it has a new home out in my shop, as it replaced my Logitech wireless mouse for my Dell laptop I use out there. By the way, that Logitech is from the late 1990's (Win 98/Win XP period)! And I don't think that one will ever wear out!
