Mice have the unusual task of being in contact with most computer users more than anything else. By that I mean it is in our hands and its entire shape is connected with us. While the keyboard is something we use more, it is not something we connect with to the same degree as the mouse because it is just our fingertips that connect with it.

Having said that, the shape of a mouse is a really key element in its success as a player in the market. There are definitely other elements too like DPI, programmable buttons, scroll wheel etc, but if it doesn't feel right the features won't contribute to the bottom line in its success like they could.

I have owned a wide range of mice ranging in price from about $20 to $80, and ranging from brands I have never heard of to Logitech. The most featured one I have is the Logitech G502 Proteus Spectrum RGB Tunable Gaming Mouse, FPS Mouse it has a great shape, super high DPI for my photo editing and other features that made it my favorite until I got the MX anywhere.

While it doesn't have the same range of features as the G502, there is no just no comparison to how it feels when you use a mouse as much as I do.
Previously when I did a lot of photo retouching, the higher DPI was a feature I really needed, but these days I do a lot of web development, and general computer tasks, and for that kind of work, the MX anywhere is a dream to use.

FEATURES:
Its cross computer feature is not something I have used because I only have one computer in my office
The TRACK ANYWHERE is amazing - I even tried it on glass and it responds the same as if it was on a mouse pad.
Multiple connectivity options are fabulous, I have the USB dongle in the computer at home and I use the bluetooth on my laptop at work.
Battery - 70 days on one charge is pretty fabulous & I am a big fan of connecting the mouse via usb to recharge.
I cannot remember the name of the feature, but when you hit the button next to the scroll wheel, you can see all your open applications on each screen that they are open on (i have 3). On a PC its like ALT-TAB, but way better :)

SUMMARY:
I know it's a fairly high price for a mouse that isn't laden with features the same way as something like the G502, but for me there simply isn't a mouse that I have enjoyed using as much. At first it felt a little small because I was transitioning from the larger G502, but now after a week, it is exactly the right size. If you are reading this review, and are in the market for the best mouse experience ever, I suggest you give this puppy a spin :)

I suffered with an aging Logitech Anywhere MX - it was getting increasingly difficult to track precisely and scrolling was also getting worse. So I tried a cheap mouse from China that cost only $9.50 but had good reviews and claimed it worked on a Mac. Yikes, not good and much worse than my aged prior mouse. So I did the research again and this time popped for the Logitech MX Anywhere 2S - great choice. Tracking and scrolling are good and the forward and back buttons work on my Mac - huge efficiency feature that I use constantly when surfing the internet. I doubt I ever will use the multiple computer features but for my usage case this mouse rocks. Also, it can connect via wireless or bluetooth. My research suggests that bluetooth is better and so the wireless receiver is sitting on a shelf. All in all I procrastinated for 6-9 months before trying to fix my mouse and hopefully this one works for years to come.

Update (Sept 2017), I got a new keyboard and the bluetooth mouse interfered with the bluetooth keyboard. I had an open usb slot so I plugged in the receiver and problem is resolved. Guess I didn't need to pay extra for the bluetooth feature as the usb receiver works just fine.

Fantastic mouse. Very responsive, nice crisp clicks, smooth scroll wheel, and pairs easily with my Mac.

I had expected this mouse to be a larger, similar to the M705. The MX Anywhere would be great for portability. I exchanged it for the larger MX Master 2S. The MX Master is perfect for desktop use, with more features and will migrate to other surfaces when necessary.
The features on both Logitech products are just awesome!

This is an awesome mouse. Very responsive with a lot of features for a portable mouse. I use it 90% for work and 10% general household use. The ability to copy and paste from one computer to another is such a fantastic feature. The customizable buttons are very nice. Default side buttons for forward and back web page navigation, the side scroll and quick scroll features on the wheel work great, although the feel took a little getting used to. The size of the mouse is perfect for me and I like that it's rechargeable. So far I've not found any surface that it wouldn't work perfectly on.

This is an excellent mouse that gives you capabilities that others don't. One, is that it works on every surface I have tried it on. One of the worst surfaces is glass (which most don't work on) and it worked on it. No other mouse I have tried could do that.Second, the ability to use the same mouse with cut and paste option across computers. If you have both Macs and PCs, this is a big deal. It is great to be able to move data from a Mac to a PC using the same mouse. Be sure to install the software included to be able to have this function.The mouse feels good in my hand and works on all surfaces. Highly recommended!

The main reason that I wanted to try out the MX Anywhere 2S mouse was for its Darkfield high-precision tracking, which means that the mouse is supposed to work at 4,000 DPI on any surface, even glass. I found that the mouse does indeed track beautifully on any surface—my couch arm, my knee, and even glass. And not just glass with a solid surface directly underneath, but even a pane of glass suspended in the air several feet off the floor. This is the best-tracking mouse I have ever used.One small drawback, which I was aware of before I got the mouse, was that you cannot store the USB receiver inside of it, like you can with a number of Logitech mice, including the M525 that I have been using. Without such storage, you have to either leaver the receiver in your laptop, where it might be damaged when moving the laptop (this happened to me before), or finding some other place to store the receiver and hope that it does not get lost.I had a pleasant surprise on reading the features of the MX Anywhere 25 that reduced some of my concern about losing or damaging the receiver. It turns out that you have a choice of connecting either with the USB receiver or through Bluetooth. It is nice to have that choice. I found that the mouse worked well either way, and that it was easy to pair the mouse with the Logitech Options software (which must be downloaded from Logitech).I had not used the Logitech Options software before, and found that it was a great way to choose the options for the left/right click, two buttons on the left side of the mouse, the scroll wheel (which also clicks left and right), and a square button on top called the gesture button. The options are basically the same as Logitech software from 20 years ago, but the graphic user interface is much easier to use than navigating through text-based menus. I had not used a gesture button before. The way it works is that you hold it down while moving the mouse forward, backward, left, or right. The default gestures are things like bringing up the Windows menu or task manager or going to the desktop, and the gesture button did work for issuing the commands. I don’t know if I would ever use it, though, as pointing and clicking on the Windows menu, for example, seems just as easy to me. I wish I could assign the key to the gesture button—that could really be useful for things like opening a link in a new tab or window. Alas, that assignment is not possible.A feature I found somewhat odd is that the mouse uses a rechargeable battery. The documentation says that plugging in the mouse to your computer with the provided USB cable for 4 minutes will charge the mouse for one day, and a full charge will last for 70 days. I don’t see the advantage—the two AA batteries in my M525 are supposed to be sufficient for three years’ use. Seems a little gimmicky to me.The feature I was most curious to try was the ability to use the mouse simultaneously with two computers, enabling one to copy text or files from one computer and pasting them to the other. This would be the coolest mouse feature ever, if I could get it to work. But here is what happened. First, it seemed that I would have to use Bluetooth connections for both computers, since you can use either the USB receiver or Bluetooth, and there is only one receiver. From the Logitech Options software (which must be run on bother computers for the dual-control to work) documentation, it looked like the mouse should function just like it does on a dual monitor set-up. That is, moving off the edge of one screen will make the cursor appear on the next screen. The trouble was, as soon as I moved off one screen, the mouse would not work on the other computer until I changed Bluetooth channels by pushing a button on the bottom of the mouse. This made moving back and forth extremely awkward and time-consuming. I got this feature to work, but it seems too cludgy to be useful. Maybe there’s a better way to do this, but if there is the documentation does not explain it well.So, aside from the disappointment of not getting the coolest feature to wor

It's pretty cool to have a mouse that does both bluetooth and usb dongle. This is now my travel mouse. I don't pull it out for quick computer use or for playing around with the laptop. When if I really need to get work done at a hotel or on the go, I like a mouse compared to a trackpad for work. This ones's really cool in that it connects with the usb dongle to my computer and it can connect to my wife's computer with bluetooth. We can both have the advantages of a mouse with her still using her very thin travel case.It's also a good sucessor to the original MX anywhere mouse. The old MX mouse had a little more weight. I think some confuse weight with quality. This still has a little bit of weight (it doesn't feel hollow), but it's lighter. The plastic still seems like quality plastic and I think it will last like all of my logitech mice have!It's got all these special features like copy and paste between two computers and such, but I don't like to install the extra software needed for these functions. I just want an awesome mouse that works on any surface!This is about the perfect mouse for me. It works on any hotel desk/table without a mouse pad and it just works. I'm happy with it and I do suggest it.
