Logitech MX Master 3 Review

Even though Windows has done a good job of bringing touchscreens to the PC world, they are still in the minority when it comes to how users interact with their hardware. The keyboard and mouse are the primary means of input which means selecting the wrong peripheral for your computer can dramatically impact your experience when using Windows (or any other OS).

For many years, I have been using the MX Master as my primary mouse but last week, I made the jump to the new MX Master 3.

There’s not a lot of ways you can review a consumer mouse other than saying “it works” but let me try to breakdown why this mouse works for me and why I recommend it to anyone who needs a general-purpose peripheral.

Is it the best gaming mouse? No. It is the best ergonomic mouse? No. Is it the best productivity mouse? No. But what it is, is the best all-around mouse – it’s the Toyota Camry of mice, the Honda Accord of input devices – it’s not flashy, it does not have RGB lighting (it does have a battery indicator) but it gets you from point A to B comfortably and is a, generally speaking, a great mouse.

The mouse has all the basic features like a very smooth (and accurate) scroll wheel, buttons in all the right places, and a thumb scroll wheel that you can map to various functions. It’s got the right amount of buttons, not an overkill that makes it hard to quickly click the desired action.

The weight of the mouse is optimal, it’s comfortable, and the rubber material should hold up for a long time based on my previous MX Master holding up well after several years of use. And the texture of the material provides plenty of grip but is also soft enough to be comfortable for extended sessions.

The design is an evolution of the previous rounded designs. The left and right mouse buttons have an angular design that slopes down from left to right whereas the previous iterations had a pointed layout. The design doesn’t really make much difference and is subjective to your tastes. For me, the look is fine and in person, it looks a lot less modern than the Logitech promo images make it out to be.

The biggest reason I decided to upgrade is that the battery on my MX Master was not lasting much longer than a day or two. The new MX Master charges via USB-C, and in one minute of charge time, can operate for three hours. A full charge, Logitech claims, will last 70 days. That being said, I would prefer wireless charging as that would mean one less cable I need to keep plugged in on my desk but Type-C is better than the older connectors.

The biggest downside to this mouse is that the battery can not be easily swapped. This was the same with my previous mouse and while you can technically open it up and swap the batteries, it’s not a trivial task and when the battery goes flat, more than likely, you will buy a new mouse.

You can use the mouse while plugged in but it’s not optimal but can be done to prolong the life of the peripheral if you truly don’t want to give it up.

Logitech does have desktop software that is easy to use to map new functions to the mouse but I only ever open that app when refreshing a PC and I need to remap the configuration to my desired settings. Just know that the buttons are easily configured and you can remap them to nearly anything your heart desires.

The scroll wheels are smooth and easy to manipulate while the left and right buttons offer enough resistant to prevent accidental clicks but not too firm to make it hard to engage the buttons. Using the dongle, I never had any connection drops with the mouse feeling precise and responding quickly to my inputs.

The mouse comes in two colors, black, and grey and at $99, it’s not cheap. That being said, for something that is your primary input device on a PC, spending a little extra may be worthwhile for the improved experience over a basic mouse.

At the end of the day, it’s a mouse that is accurate, scrolls incredibly smoothly, and is comfortable as well. There are thousands of mice available but for me, this is my preferred mouse and highly recommend it to anyone in need of a new input peripheral.

    Brad - Do you know how it compares with the MX Master 2?


    My MX Master 2 is kind of annoying as the only micro-USB device on my desk, but it looks like the MX Master 3 is just a minor step-up vs. a must have replacement over the MX Master 2. Any thoughts on that?

  2. BBoileau

    I have the original MX and like it for all the reasons you state. Battery degradation not present. I will wait for a wireless charging with a mouse pad as the charger.

  3. mestiphal

    I personally liked the Performance MX better, but it seems they don't sell it anymore. when it's time to change, I might jump to the MX Ergo for the trackball.... the Logitech TrackMan Marble Wheel was my second "mouse"

    I'm looking to get a mouse to use with software like Photoshop and Lightroom. I don't currently own a mouse as I am working off a MacBook Pro. Should I go for the MX Master 3 or 2s?

      In reply to iwan_tottle:

      Depending on the price, you can have either way. 3 isn't of a huge upgrade, it's an incremental one. Heck, even the first-gen Master is fine if you find one cheaper. If you need something cheaper (but a good ergonomic mouse regardless, not a mouse for small hands) try the M720 Triathlon.

    such a poor design, they put the usb-c port in front of the mouse, in this way you can eve use the mouse while charging, they should have learned from apple /s

  6. bluvg

    70 days of battery life seems really short to me...

  7. anderb

    Embedded battery? No thanks. M570 Trackball FTW!

  8. harmjr

    Why. USB-c charging but no usb-c dongle. What the hell Logitech.

    • IanYates82

      In reply to harmjr:

      Because so many PCs and laptops have one, maybe two usb-c ports (and if just one, it could be thunderbolt), but they'll often have twice as many classic usb ports.

      Many desktops still don't have usb-c at all

      Most consumers, if they've seen it, know it as how they charge their Android phone.

      It's just not there yet in ubiquity...


      Brad: there was no mention of Bluetooth. Does it support that at all? Deal breaker, for me, without that unfortunately

    • wright_is

      In reply to harmjr:

      Because if it has USB-C, it probably has Bluetooth as well, so you don't need the dongle.

  9. RobertJasiek

    The mouse uses Logitech's Unifying protocol, which has security gaps.

  10. SvenJ

    Lefties, disregard.

  11. ebnador

    I've had several of the MX Master series and I agree they are the best everyday mouse on the market. I just wish for $99 dollars it was Bluetooth instead of requiring the dongle.

    Once I started using a vertical mouse for ergonomic reasons I never wanted to go back to the conventional model.

    And in the branch of verticals a 20€ model does the job although out of curiosity I'd like to have a test run on the Logitech model some day.

    • Leebing

      In reply to My Hell baby speaking:

      I tried the Logitech vertical mouse to help with my tendinitis and it was horrible. Slick surface made it hard to keep hold of. The buttons were very stiff and made clicking an actual effort. The scroll wheel was a normal, hard clicking, slow wheel. Not like the Logitech infinity scroll wheel in their other mice. I have been happier with the 20-30 dollar vertical mouse and returned the Logitech vertical.

      • wright_is

        In reply to Leebing:

        The Logitech vertical mice are also horrendously expensive.

        We had one of the earlier vertical mice, cost around 100€. Last summer we had a new employee, who needed one. I got an Anker vertical mouse for 20€, it was a lot better and cheap...

    Still rocking my MX Performance for 4 years with no problems. If it break apart, I might try a Master. Dad got an Triathlon M720, a cheaper but excellent alternative to these. Can't recommend enough Logitech mice, specially the Unifying compatible ones.


    Previously Dad used Microsoft combo (Keyboard+Mouse) until the wireless receptor stopped working (and we had no other option than shelve the entire set), but then I recommended him using Unifying devices and well, and right now we got a couple of devices lying around (mice, keyboards, et cetera) that are compatible with no problems.


    Even my ex, I gave her a Logitech wireless mouse and never had any complaint.
