Logitech MX Master 3 Wireless Mouse Review: Successfully reinventing the wheel

I know it's sad to call a mouse your best friend, but when it comes to boosting productivity with a single piece of hardware, the Logitech MX Master 3 (99 USD / 99 GBP) is the term BFF worth, because I'm not I'm not about to separate from him soon.

Thanks to the innovative electromagnetic scroll wheel and the customizable settings per app, you can set this mouse to be an ideal companion for any software you use. In addition, you can control and send information to as many as three PCs (Windows, MacOS, and / or Linux) so that the mouse can be present at each step of multi-device activity.

If you're not that type If you're a power user or just looking for a fast, light, or eye-catching mouse, you'd better look for a cheaper or special gaming mouse.

Design and comfort

The biggest design change that Logitech with the MX Master 3 opposite the MX Master 2S and MX Master are in the scroll wheel, which has been updated with electromagnetic technology and called MagSpeed, which allows you to switch between fluid and precise scroll mode. This is the only part of the mouse made in Switzerland (the rest in China). Although the wheels of the older MX Master mice can scroll in small, line-by-line increments or rotate freely, they make noises. Even if you scroll line by line and each line produces a noticeable frictional click, the MX Master 3 is quiet. In addition, in free play, the wheel spins much longer and smoother than the predecessors of the mice or other mice I've ever used.

That's how it works. The machined stainless steel wheel is open in the middle, where there are electromagnets. In the ratchet mode of the mouse, where the wheel rolls line by line for precision, the two electromagnets are oppositely poled, so that the magnetic force flows through the teeth of the gear and interacts with the outside of the steel wheel. When the teeth of the gear are closer to the magnet, you feel more force, if not less force, resulting in friction with each interlace.

When the wheel rotates fast and without friction in Free Spins mode, the electric current flows inside. The module changes the polarity of the electric magnets, so that now the magnetic force no longer interacts with the steel wheel and the wheel as fast as possible – like a spinner – goes through 1000 lines per second. It's different from the simple click in the wheel and scrolling, as it offers more precision, especially if you want to stop.

Move by magnetic pulling. The wheels of the wheel do not touch anything, and Logitech has told me that the mouse will last longer than its predecessors (Logitech did not extend the warranty).

You can switch between ratchet and freespin by pressing the button under the scroll wheel or using SmartShift (activated in the software) to adjust the mode according to the movement of the wheel. SmartShift is very helpful when scrolling through long documents, PDFs or spreadsheets. Freespin quickly drove me past many pages until I reached the desired section, and when I put my finger back on the steering wheel, I was able to do more precise scrolls to find the desired heel.

The MX Master 3 differs from its predecessor with a new key layout and a revised thumb pad to make the operation more comfortable and intuitive. The thumb buttons – the wheel, the forward and back buttons – are positioned vertically above where the thumb rests. The thumb rest also has a gesture button that can be programmed to perform an action when pressed and perform other actions when pressed. Move the mouse in one of the four directions.

I could press all four buttons without looking down, so they're actually handy. However, I would like the thumb rest button (located in the same place as earlier models) to be closer to the body of the mouse, or even directly to the side, as I move my thumb outward and press down with the side of my thumb had to use.

The mouse measures 2 x 3.3 x 4.9 inches, is rather chunky, especially in height, but this height gives the palm a firm but gently textured resting place. Regardless of whether you use a hand or claw grip, the lower knuckle of my pointer was particularly pleasing to the mouse's raised hump.

The thumb rest is textured and the palm rest, where you keep your little finger, provides the same feeling of lasting comfort. The buttons for right and left click are a bit softer. It's not the quietest mouse in the city, but definitely an upgrade from a flat plastic case.

The wireless mouse uses a USB Type-A receiver and connects to a PC over 2.4GHz up to 10m (33ft). If you use other Logitech products with the Logitech Unifying Receiver, you can only use one receiver for up to six products. This is very helpful if you only have a few ports left. You can also connect without the receiver via Bluetooth Low Energy. This is especially useful when pairing a device without USB Type-A ports.

At a weight of 0.3 pounds, the mouse feels heavy, especially if you're used to using a lightweight gaming mouse. Compared to the Razer DeathAdder Elite (0.2 lb) eSports mouse I normally use, it's a bit harder to do 3 big moves with the MX Master.

Below the mouse is the power button and a button to control the desired PC mouse to control out of three possible ones. This may seem impractical, but if you enable Logitech's Flow feature, which allows you to control up to three PCs with the same mouse (more on that later), you do not have to press a key to move the mouse from one screen to another move. There is also a USB-C port for connecting the supplied cable and for loading the mouse.


The new MX Master 3 has the same sensors as the MX Master 2S, the darkfield sensor from Logitech, with a maximum CPI (number per inch, sometimes called DPI) of 4,000, which is high for a productivity mouse (low for a high-speed gaming mouse). You can adjust the speed through the software, but only with a slider, not precise numeric increments. Nevertheless, the mouse kept up with all my movements, from fast, crazy and fast movements to slow and precise movements in Excel spreadsheets.

The laser sensor can be used on any surface, even on glass, if it is at least 4mm thick. I tried it on various surfaces, glass, a wooden desk, a plastic table, a suede couch, a marble top and a bed, and never had a problem.

The newly invented scroll wheel of the MX Master 3 means the flexibility to switch between long, fast scrolls. – like looking for something in a PDF file or spreadsheet – and precise line-by-line scrolling – like reading an article – with a touch, and the mouse can easily read which mode you want with your touch (though it also ratchets or Freespin can select as the only mode). Thanks to the key mapping, you can access almost all keys (with the exception of the scroll wheel mode changer) without having to take or pay attention to the mouse.

You can make the mouse even more user-friendly by using key functions in the Logitech Options software. You can not assign anything to the right and left click buttons, but you can change their functions. Profiles can be set per application or for all apps.

The mouse software comes preinstalled with profiles for Adobe Photoshop, Adobe Premiere Pro, Final Cut Pro, Google Chrome, Safari, Microsoft Edge, and Microsoft Office. In this case, the profiles are automatically implemented when the software is downloaded. This is a new feature in the MX Master series. Logitech told me that some apps have similar profiles to improve muscle memory.

Setting functions via app should help users to fight distractions. For example, in Photoshop, the brush size key combination is on the keyboard. However, you do not have to look away from the screen with the mouse.

The prefabricated profiles were created logically for typical use. For example, if you scroll the thumbwheel in Chrome and Edge, the tabs are swapped, scrolled horizontally in Excel, and zoomed into PowerPoint and Word. In Word, Excel, and PowerPoint, the forward and backward selection buttons are both repeated and undone, but Chrome in Edge rolls back or rewinds a page in the history.

If you do not like the setting of Logitech With a certain software you can of course disable the profile or create your own. Since there are often multiple Chrome windows open at the same time, I've programmed the gesture button to show the desktop in Chrome. I also chose SmartShift to automatically switch between ratchet and free spin modes, and made sure that the Rad Mode Shift button opens a new Chrome tab.

Although not designed for games, with the ability to programmatically program buttons depending on the software and wheel, the mouse can placate players during long gaming sessions or when scrolling for different weapons. However, competitors may prefer something lighter, while others may miss the RGB lighting.

One mouse, three PCs

Logitech equipped the MX Master 3 with its Logitech Flow technology, allowing you to control and send files with an accessory. Text and images on up to three PCs (other products using Flow can be found here). To use it, the Logitech Options software must be installed on each PC, and to transfer information, the devices must be on the same Wi-Fi network. The process is similar to the Windows 10 Nearby Sharing feature, which lets you send documents, photos, and URL links to another PC if they both share the same Wi-Fi and use Bluetooth. However, you can not copy and paste any text or image, or control other PCs on a device, as Flow can do. Note that Flow probably will not work if you do not have a computer with Bluetooth LE or more than one Logitech receiver.

After pairing the mouse with your PCs and enabling Flow, you can arrange the screens in the software and move the cursor to the next screen as you go to the edge or as you go to the edge and drag the cursor. Keep the button pressed (your choice). Designed for users like programmers, engineers and other professionals. It's fantastic for someone like me who often uses my work PC and a test device or even a personal computer at the same time.

Flow has worked just as it should on the MX Master 3, and the mouse moves smoothly across three PCs as if they were one. Copying and pasting was also quick and easy, whether it was text or folders with multiple file types (PDFs, Word documents, Excel spreadsheets and images). Every data transfer is protected by AES-256 encryption.

Features and Software

You can plug in the MX Master 3 and get started right away, but if you're using it with multiple PCs or you want to program one of the buttons, you'll need the free Logitech Options software. Power users will appreciate the ability to change key functions or point / scroll settings based on the specified app.

Programming the keys is very simple and requires no technical knowledge, since Logitech is using it makes a variety of options very easy. It even recommends actions for specific gestures – opening a new Chrome tab by clicking on the scroll wheel was one of them. The software thinks like users as Logitech creates its profiles from user data and profiles created with the MX Master 2 itself.

The software also has Duolink mode, which allows you to use Fn in combination with specified mouse gestures to execute a command. The software can store two different profiles: Standard and Duolink. With this software, a combination is possible for everyone.

Optimization options that allow the mouse to work exactly as you like it. You can make the settings universal or app-specific. The app also has a link that explains the various modes of the scroll wheel. This ensures that you do not need much technical know-how to use the peripheral device. It's that easy. One Flow is enabled and it is very easy to adjust the edge of the mouse jump PC. And I appreciate being able to move the devices (up / down or left / right) to reflect the actual physical layout of my devices. When Flow is enabled, the mouse moves to the next PC by moving to a specific edge or holding down the Ctrl key and moving to an edge. The devices are even color-coded and the device you use gets a blue-green mark to avoid confusion. ]

You can also enable a convenient taskbar icon that you right-click to turn off Flow or access the settings.

Battery Life

Logitech indicates that the MX Master 3 has a battery life Up to 70 days of full charge (via the mouse's USB-C port and the supplied USB-C-to-USB type) A cable) and up to three hours with a one-minute charge. The software has a battery indicator with three bars and next to the thumbwheel is a small light that turns red when the juice runs out.

I did not have the mouse long enough to confirm the 70 day demand. However, I used it intensively for about 32 hours (4 working days) and left it on for 72 additional hours, and the battery gauge was still full.


You say you should not reinvent the wheel. But if you can make it smoother, faster, quieter, more responsive, and more entertaining, why not? Logitech has done so with the MX Master 3 and has improved its usability with a highly customizable key layout that is almost completely navigable without having to take your hand off the mouse.

For $ 100, this is a premium mouse. They pay partially for the ability to control multiple PCs and make adjustments per app. If you do not need them, it's better to buy something cheaper or if you're a gamer, a fast gaming mouse.

For professionals who frequently switch between devices and software, the MX Master 3 is a great choice and can now be integrated into your new favorite productivity tool.
