Logitech’s MX Master series of wireless mice is renowned for its comfort, customization and ability to switch seamlessly among up to three different devices. If you’re working with more than one computer at a time, the company’s Logi Flow feature is really helpful because you can drag the mouse pointer across from one desktop to another and the wireless connection will switch with you, even taking the clipboard contents along for copy and paste.
Up until now, if you wanted a wireless keyboard that would work with Logi Flow, you were limited to Logitech’s MX Keys series. But no one who is serious about their typing would lay fingers on a non-mechanical keyboard if there was a better option. Now, Logitech has introduced the MX Mechanical and MX Mechanical Mini, two wireless MX keyboards that use Flow and come with a choice of mechanical switches.
The $169 Logitech MX Mechanical is a full-size, 110-key keyboard while the $149 MX Mini offers a more compact layout with just 84 keys. Both keyboards are low-profile and available with a choice of clicky blue, linear red or tactile quiet brown low-profile switches, all of which are made by Kailh. We tested with two units: an MX Mechanical with blue switches and an MX Mechanical Mini with browns. In either form factor, the keyboards offer a typing experience that’s on par with many of the best wireless keyboards, a ton of customization options and easy switching between PCs. However, you have to be comfortable with a low-profile design, which limits your choice of wrist rests.

Design of Logitech MX Mechanical / Mini
The Logitech MX Mechanical and MX Mechanical Mini share a boring, but professional aesthetic that looks fairly premium and won’t offend or excite anyone. The thin keys are two shades of gray with letters and numbers having the lighter hue and special / modifier keys getting the darker one. The case sides and back are the same dark gray plastic while the area under the keys is a matte aluminum plate.
Logitech designed the keyboards to fit into even the most design-conservative workplaces and the backlight, which can only show pure white, follows suit. However, you can configure it to use a variety of lighting effects, including static contrast, waves and breathing. No matter which effect you choose, the backlight uses an ambient light sensor to determine when it should turn on so, if you’re in a brightly-lit room, it will save power by staying off.
If you’re not used to using a low-profile keyboard, the short height of the Logitech MX Mechanical and MX Mechanical Mini will take you by surprise, and not necessarily in a good way. Both devices are just 1.02 inches (26.1 mm) tall with their feet flipped out and about 0.7 inches (17.8mm) when flat. That’s nearly an inch lower than the Akko 3098B on its highest of two feet and 0.5 inches (12.7mm) lower when flat. The keyscaps and switches, which are not hot-swappable, are also low-profile.
A shorter keyboard means that you can’t use a standard-height wrist or palm rest, because you don’t want a rest that’s too tall and forces you to poke downward at your keys. If you don’t use a wrist rest, this won’t matter to you, but I can’t live without one. When I couldn’t pair my HyperX Wrist Rest with the MX Mechanical, I was very frustrated. Fortunately, there are low-profile wrist rests on the market and Logitech even makes one, which was designed originally for the MX Keys but works fine with the MX Mechanical.
I bought the $20 MX Palm Rest, which is just 0.31 inches (7.8 mm) tall and 16.5 inches (419 mm) wide, which makes it ideal for the MX Mechanical but overlong for the MX Mechanical Mini. It doesn’t have the soft gel or memory foam that I like to see in my rests, but it is fairly soft and has a nice, smooth surface. However, the bottom doesn’t grip the desk well enough and it can slip out of place sometimes.
The fact that they’re so thin makes them easy to put in a bag. The Mini fits perfectly into a bag on the go, though the longer, full-size keyboard sticks out of anything but the largest backpacks.
Putting height aside for a moment, the MX Mechanical is 17.1 x 5.2 inches (433.9 x 131.7 mm) and 1.8 pounds (828 g) which is a bit more compact than Razer’s full-size Black Widow V3 Pro (17.7 x 9.8 inches, 450.7 x 248.4 mm). The Mechanical Mini is 12.3 x 5.2 inches (312.6 x 131.7 mm) and 1.3 pounds (612g) which is much smaller than the iQuinix A80 Explorer (12.6 x 6.3 inches, 3.5 pounds).
Layout of Logitech MX Mechanical / Mini
The Logitech MX Mechanical has a full, 110-key layout, including a numpad, arrow keys and a block of keys for Ins, Home, Del, End, Pg Up and Pg Dn. Above those keys are three dedicated buttons to switch to each of the three device profiles, no key combo required.
Above the numpad sit four shortcuts for calculator, search, lock and show/hide desktop. Annoyingly, Logitech does not provide a dedicated print screen key, even though most full-size keyboards have one of those and don’t have a calculator button. However, using the Options+ software, I turned the show/hide screen key into a print screen key.
There are no dedicated media keys but, keys on the function row double as brightness, mute, emoticon and media keys. There are, however dedicated volume up and down buttons to the right of F12. You can toggle function key mode on and off by hitting Fn + Esc.
The MX Mechanical Mini has only 84 keys in a very compact design that has all the hallmarks of a 75 percent layout. There’s no number pad, but there are arrow keys and a right column with Pg Up, Pg Dn, Home, End and Delete keys. As on the MX Mechanical, the function row doubles as a media key row but, instead of adjusting brightness, the first three function keys double as device switching keys that take you to profiles 1, 2 or 3. You also get a play / pause button but no next or previous track buttons.
Since the keyboards are made to work with either macOS or Windows computers, one thing you’ll notice is that the Alt, Ctrl and Windows (Start) keys are all labeled with both Mac and Windows legends. You can switch between Windows and Mac layouts by holding the function key and the letter P for Windows or O for Mac.
Key Switches and Caps on Logitech MX Mechanical / Mini
The Logitech MX Mechanical and MX Mechanical Mini come with your choice of clicky blue, linear red or tactile “quiet” brown switches. All of the switches are low-profile Kailh Choc V2 switches, though Logitech says the brown switches have been specially tweaked to be quieter than the standard ones. Unfortunately, if you don’t like them, you can’t remove them as they are not hot-swappable.
Kailh Choc V2 switches have 3.2 mm of travel with 1.3 mm of pre-travel before the actuation point. The blue and red switches require 43 grams of actuation force while the official brown switches require 45 grams. However, it’s unclear if making the browns quieter caused Kailh to change these specs. In our experience testing in the office, the brown switches were not appreciably quieter than the blue ones; they just had a lower, less obtrusive pitch.
For reference, full-sized Cherry MX Blue, MX Red and MX Brown switches have 4 mm of travel with 2.2 mm of pre-travel before they actuate. The MX Blues require 50 grams of force to actuate while the Browns and Reds require 45 grams. With less travel and force needed, the keys on the Logitech MX Mechanical / Mini feel much lighter, making them good for fast typing. However, even with the reduced travel of 3.2 mm, I never felt myself bottoming out.
The ABS keycaps are pretty flat with a slight indentation that reminded me of the caps on laptops. They easily picked up and showed my finger oils, making the keyboard look a little greasy after I’d only used it for a little more than a week. In theory, you could change out the key caps, but you’d need ones that work with low-profile switches. I tried putting one of my Akko ASA keycaps on one of the switches and it snapped on easily, but it made the key stick a bit when I was pressing it.
Typing Experience on Logitech MX Mechanical / Mini
I tested the Logitech MX Mechanical with blue clicky switches and the Logitech MX Mechanical Mini with brown tactile switches. I always prefer clicky switches so I used the Mechanical as my daily driver for a week and found that it offers truly fantastic tactility and just the right amount of resistance and travel.
I normally use a full-height keyboard with terminal-style ASA keycaps and Kailh Box White switches so it took me about a day to get used to the low-profile keys and their mostly-flat caps. However, once I adapted, I was as fast as I ever have been and made fewer errors too. On the 10FastFingers typing test, I scored 109 words per minute with just a 4 percent error rate, when I normally am at 100 to 105 wpm with the same or a slightly higher error rate. I think the slightly-reduced travel and actuation force of the low profile keys helped me work faster.
Typing on the MX Mechanical keyboard with blue switches was not just speedy, but also comfy; I didn’t have to push as hard with my fingers and yet I also didn’t bottom out. However, the fact that I couldn’t use my favorite wrist rest, the HyperX Wrist Rest, and had to use the inferior MX Palm Rest took away from my comfort.
My colleague Andrew E. Freedman spent more than a week using the MX Mechanical Mini with brown switches as his daily driver at work on a Mac, and he enjoyed the typing experience. He typically uses tactiles switches, and found them to be comfortable, though louder than the silent switches he uses on his own personal board. I found that the brown switches were not springy enough for my taste (as I find most browns), but I was able to hit 105 wpm and about a 3% error rate on the typing test.
Interestingly, despite Logitech’s claims, the brown switches did not seem significantly quieter than the blue ones in our tests (to several of our ears, anyway).. As we clacked on them at our adjacent desks, both were clearly audible to our nearby coworker, though the clicky blue switches were much higher pitched and more shrill. So, if you’re concerned about keyboard noise, the brown switches give off less offensive noise, but it’s not as if you can’t hear them.
Connectivity and Logi Flow on Logitech MX Mechanical / Mini
Both the Logitech MX Mechanical and MX Mechanical Mini can connect to up to three different devices via an included Logi Bolt USB dongle or Bluetooth LE. While three profiles is probably enough for most people, competitors offer even more. For example, the Akko 3098B can have up to five different connections, including three Bluetooth profiles, a 2.4-GHz dongle and wired mode. The MX Mechanical / Mini cannot transfer data over its USB-C connection, so a wired mode isn’t possible. (You can still use it while it’s charging, however, just over the wireless connection.)
The keyboards come with a single Logi Bolt dongle in the box that’s paired to the keyboard and will work right away without software, though if you want to pair with a Bolt dongle you got elsewhere – perhaps with a MX Master 3S mouse – you’ll need to use the Logi Options+ software to make that happen. I primarily used a Bluetooth connection, and I found it as stable as using the Bolt.
Note that Logi Bolt dongles don’t work with older Logitech devices that require a Unifying Receiver and Unifying Receivers won’t connect with the MX Mechanical. Connecting via regular Bluetooth LE requires no special dongles or software.
Whatever method you use to connect to your devices, you have two ways to switching them: either manually or via Logi Flow. If you wish to switch manually, the MX Mechanical has three dedicated Easy-Switch keys labeled 1, 2 and 3 while the MX Mechanical Mini assigns these to F1, F2 and F3 which you must pair with the Fn key (or convert your function row to a media row). In my testing, switching among a Windows 10 desktop, a Windows 11 laptop and a Raspberry Pi (running Linux) was quick and painless, with a delay of less than a second between the time I hit the Easy-Switch key and when the connection changed.
One of the main selling points (if not the main selling point) of the Logitech MX Mechanical and MX Mechanical Mini are their ability to use Logi Flow in concert with an MX Master mouse. The goal is to turn multiple computers into one giant desktop. With an MX Master 3S and an MX Mechanical connected to both my laptop and desktop, I was able to switch between the two devices simply by dragging my pointer off of the right side of the desktop’s screen and onto the laptop’s display. I also copied and pasted content between the two computers.
To set up Logi Flow, all I had to do was click the Flow tab in Options+ after selecting my mouse (this only works if you are using it with a compatible Logitech mouse) and then drag boxes representing each computer around so that laptop box was to the right of the desktop one. That told the software to switch devices once I moved to the right. I could similarly configure Flow to see my laptop as being located above, below or to the left of my desktop. To make the MX Mechanical work with flow, I just had to turn the Link Keyboard option on.
My desktop has four monitors laid out in a 2×2 configuration. One issue I had with Flow is that, whether I dragged my pointer to the right of the top right monitor or the bottom right monitor, it still moved to the laptop, which was sitting on the bottom right of my desk. So I ended up accidentally moving to my laptop several times, until I enabled another option in Flow, which only changes the device if you’re holding down the CTRL key while you drag your pointer off screen.
A word of caution about Flow: it only runs on devices that have Logi Options+ installed. So, if you are working with a Raspberry Pi, a Chromebook or an Android tablet, you’ll have to switch to those manually.
Software and Customization of Logitech MX Mechanical / Mini
Logitech’s Logi Options+ software, the next-generation of its Logi Options app, is powerful and easy-to-use, but still leaves some room for improvement. When you launch Options+, you’re given a list of your currently-installed Logitech devices and a button to add new ones.
If the MX Mechanical isn’t paired yet, you can click the Add Device button and then choose among wireless connectivity options: Bluetooth or Logi Bolt (if the dongle is plugged in). If you choose Bluetooth, you’ll be kicked to Windows’ Bluetooth menu but, if you click Bolt, the pairing process will take place in the app.The first time you connect the MX Mechanical / Mini, Options+ will give you a tour of the device, showing you what you can configure on it.
The Logitech MX Mechanical / Mini has four tabs in Options+: Keys, Backlighting, Easy Switch and Settings. Keys, the most important of these, shows you a complete map of your keyboard with reprogrammable keys highlighted by a white box.
To change a key’s mapping, all you need to do is click on it and then choose from one of about four dozen options, including Search, Lock, adjust brightness and zoom in / out. You can also assign a keyboard shortcut to a key or have it open a particular file or folder. One of the built-in options is screen capture (aka print screen), so I reassigned the Show / Hide desktop key to use that functionality.
Unfortunately, Options+ doesn’t let you remap any key you want. It only works with the function keys, the Insert / Del / Home / End / Pg Up / Pg Dn block and the four keys above the numpad (on the MX Mechanical only). That’s a missed opportunity, because some folks would like to remap their numpad or their arrow keys or maybe even characters they don’t use much. It’s your keyboard, so why shouldn’t you be able to remap the A key if you want to? You can use a third-party solution such as SharpKeys if you want to, but Options+ should let you do this.
The Backlighting tab allows you to choose the backlight pattern from among six options. These are Static, Contrast, Breathing, Waves, Reaction and Random. You can also disable the backlight entirely from here. However, you can also switch among these options by hitting the Fn + volume down key.
The Easy-Switch tab does nothing more than show a list of which three devices your keyboard is paired with. You can’t delete or add pairings from here. But must use standard Bluetooth or Logi Bolt pairing to make a change.
Finally, the Settings tab contains a few additional options, including enabling battery saving mode when the battery drops below 10 percent, forcing the keyboard to stay in a Windows layout, toggling the backlight or changing the function keys back into media keys and vice versa. The latter two options can be performed by keyboard shortcuts, so they aren’t strictly necessary here. You can also check for firmware updates and back up your settings.
Battery Life of Logitech MX Mechanical / Mini
Logitech claims that both the MX Mechanical and MX Mechanical Mini get 15 days of battery life if the backlight is on and up to 10 months of endurance with it off. I didn’t have time to test these claims scientifically, but after a week of use with the backlight mostly off, the MX Mechanical still had 95 percent of its battery left, according to Logi Options+.
Both keyboards charge via USB-C and come with a USB-C to Type-A cable in the box. Though the keyboard can’t act as a wired device, it can charge while connected wirelessly. So if you’re running low on juice, you can plug it into your computer’s USB port while you work.
Bottom Line
There’s a lot to like about the Logitech MX Mechanical and MX Mechanical Mini keyboards. Both offer an excellent typing experience, powerful customization via software, long battery life and easy switching among devices. However, at $169 for the MX Mechanical and $149 for the MX Mechanical Mini, these peripherals are more expensive than less well-known competitors with more features and better aesthetics.
The Akko 3098B, for example, goes for just $98 and works with up to five devices, has hot-swappable switches and comes with stylish but still conservative ASA-style key caps. However, Akko’s keyboard doesn’t come with very good switches by default — if you want to bring your own, you’d have to budget another $50 or so to buy them, at which point you’re closer to the cost of the MX Mechanical anyway.
To really make the most of the Logitech MX Mechanical / Mini, you need to be using an MX series mouse such as the MX Master 3S, which will allow you to switch devices via Logi Flow. And you need to be OK with, if not excited about, working with low-profile keys and a low-profile wrist rest. However, if you can afford the premium, Logitech’s keyboards will make you more comfortable and productive.
