The Logitech MX Master 3 is a Wireless Bluetooth / USB wireless ergonomic high precision mouse with programmable buttons, individual settings per app, an easy to use interface, and an elegant and solid build.

Specs on Logitech’s flagship mouse includes Logitech’s stable and precise Darkfield Laser Tracking which works well even on surfaces with irregularities such as scratches, cracks, dust, grease, or other particles.

Logitech MX Master 3 Review

Logitech MX Master 3

The sensitivity of the mouse goes up to a high 4000 dpi, with the adjustable sensitivity range being 200 dpi to 4000 dpi, in steps of 50 dpi up or down.

It features both vertical and horizontal silver metal scroll wheels, 7 buttons of which most are programmable and one has gesture support, a rechargeable 500 mAh battery, and underneath it has an on/off button and a button for switching between 3 different devices.

Used simply as a regular mouse it’s compatible with all major operating systems, including iPadOS, Android, Chrome, and Linux, but the Logitech Options user interface that lets users adjust all available settings, is only available for Windows and Mac at the time of the writing.

If you’re connected to the internet, the Logitech Options interface should start to download automatically if you insert the USB Receiver. If you just want to use it with the Bluetooth in your computer, you can download it manually instead.

Once installed, the interface will quickly take you on a tour through the settings and let you start setting up the MX Master 3 mouse for your purposes.

The left and right mouse buttons work like any other mouse buttons, and make the typical mouse click. But the “Magspeed” scroll wheel between them has a click function and can be used for step-by-step precision movements, or for spinning freely and quickly if you want to scroll some distance fast or effortlessly. It is light to use, but still precise, so that’s some good engineering.

The scroll wheel can change its modus from spinning freely without any feeling of resistance (and no audible sound), or if you click the mode change button above the wheel, it will go into the traditional ratchet feel, where you feel each step of the scroll.

A button to the left of the thumb rest can be held down while pushing the mouse in either four directions for gesture control, like for instance to alternate between different desks. It can also be used for quick access to the sensitivity adjustment.

Above the thumb rest there’s the thumb scroll wheel which has enough resistance to be precise, but not so much that it needs force to use. So it stays in place well.

The silver thumb scroll wheel can be set up for different functions per app, like zooming in and out, switching pen sizes in photoshop editing, horizontal scrolling, and so on. The two thumb buttons are nearly silent, and have nearly no click sound to them. You can feel when they are clicked instead.

These two buttons are pre-programmed as forward and back buttons, but you can program these buttons to do whatever you want in the interface.

The Mouse comes with a set of preset functions per individual app already, where the main scroll wheel can even be held down and used to pan in Adobe Photoshop and Premiere, or in browsers it can be used to open up a link in a new tab.

A snippet from Logitech’s user interface

The user friendly interface takes owners through the functions anyway, and it’s very visual, with interactive photos of the mouse in the instructions that lets you pick a button or wheel you want to program.

The buttons can be set to whatever you want it to, so it all depends on your need for shortcuts. So you can set up shortcuts to volume, music tracks, video editing functions, cut and past functions, adjust brightness, lock you device, change language, access email, calculator, anything you like to make your work go faster and more efficiently.

In the interface you can either use your mouse pointer to click on any of the buttons you want to program, or simply pick any app/program you have installed on your device, and then set up any individual profiles for how the mouse works with that program. So you could for instance set up the mouse functions differently for two different browsers.

The mouse pointer speed or sensitivity can be adjust from very slow, to faster than most people can use accurately, so every person can find just their own perfect mouse sensitivity level with this mouse.

I always recommend using a mouse mat as often as possible, just so I know that I get a more uniform experience, but I’ve tested it on glass tables, wooden kitchen tables, polished office desks, and a large book, and it works well and precise on all surfaces. Of course, with any mouse it’s sensible doing a quick swipe of a surface first and and making sure that no dust covers the mouse underneath if accuracy has started to suffer.

Additional features includes Logitech Flow which lets you transfer or cut and paste data from one computer to another quickly just using the mouse.

The battery life of this Logitech mouse is very good, and it can be used while charging too. A long USB A to USB C charger cable is included and with fast charge support it can be charged up for a few hours of use in just 1 minute, while a full charge can last for over 2 months.

A small LED next to the thumb scroll wheel will tell you what the batter status is and the light will turn green once it’s fully charged up.

The materials gives the mouse a bit of texture you can feel, so it doesn’t stick as much as a plain plastic mouse with polished surfaces if you use it for a longer period of time.

Logitech’s Master MX 3 seems to fit a large number of hand sizes since the ergonomic shape makes sure that a larger hand is pushed back a little, while a smaller hand can still clasp it. So that seems to make it a good all-round mouse.

The length of it from front to back is 4.92 inches or 124.9 mm. The total width is 3.32 inches or 84.3 mm, but the part you clasp between your thumb and ring finger is about 60 mm, which is the industry standard.

I measured the weight of the MX Master 3 to 140-141 grams, which is about twice the weight of a typical cheap 70-75 grams plastic mouse. The benefit is that it makes the MX Master 3 more stable and precise, so even when test switching between different computer mice for the same tasks, I haven’t found a downside to that yet.

The conclusion in my Logitech MX Master 3 review is that this is a very useful rechargeable, wireless, high precision mouse for coders, developers, and anyone else who will benefit from having personalized shortcuts to save time and energy so that they can accomplish more with just the click of a button.

With an infinite number of shortcuts and adjustments, high precision, ergonomic design, a well design user interface, and 2 year warranty, I haven’t fond anything I don’t like about it yet.
