Logitech’s popular MX Master productivity line continues with the MX Master 3S. It has the same ergonomic shape and set of features as the previous Logitech MX Master 3, but there are a few important changes. This version has click buttons that are quieter and a better sensor with a wider CPI range. This makes it better for use with displays that have a higher resolution. It also uses Logitech’s new BOLT receiver, which is supposed to work better in crowded wireless environments and provide better security than the older Unifying Receiver, which was used by earlier MX Master models.

A new flagship Master Series
I make no secret of my affection for the MX Master 3. I adore it so much that I purchased two – one for home and one for the office. I referred to it as “peerless,” and that still holds true today. It is still the undisputed king of productivity mouse nearly three years after its release. But three years is a long time in the world of technology, so Logitech has gone and improved it even further. The modifications are subtle but significant, so let me tell you about this new mouse.
Some may object to the lack of macro keys.
Seven buttons is sufficient for me, but some may be disappointed by the lack of macro keys. You have one spare button on the thumb rest without compromising your forward and back buttons, which may be an issue if you rely on mouse-based shortcuts rather than keyboard-based ones.
In Logitech’s defense, the Logi Options + app allows you to completely remap every function on the mouse. As a result, a user could remap the scroll select button, as once they select a preference for the scroll wheel, it doesn’t do much. Personally, I wouldn’t trade ergonomics for extra buttons, and I rarely use the thumbpad button, despite having it set to take a screenshot – a PC function I use frequently when working. I type on the keyboard.
The two-scroll wheel mechanism is also wonderful; I find myself constantly using the horizontal scroll wheel. It’s a game changer for adjusting brush size in Photoshop, and it’s also fantastic for ordinary web browsing.
The Logitech MX Master 3S’s style and comfort
You may be excused for not being able to tell the MX Master 3S apart from the Logitech MX Master 3 if you’ve seen the older model. The design hasn’t altered at all, but the color palette has somewhat expanded to include graphite, black, and light gray in addition to the original black and mid-gray. The black MX Master 3S will only be sold at physical stores, according to Logitech. The light gray is essentially white and looks fine, but it is more likely to show dirt than the graphite color, which is about as plain a shade of gray as one can imagine. Although I wish Logitech would offer more daring color options as it did with the “Midnight Teal” MX Master 2S, the objective here is to have a fairly understated appearance that won’t draw too much attention at the office.
The MX Master 3S is not a little mouse, measuring 3.3 x 2 x 4.9 inches (84.3 x 51 x 129.4 mm) and weighing 0.31 pounds (141g), but it is comparable to rivals like the Razer’s Pro Click (3.1 x 1.8 x 5 inches, 0.23 pounds). It is well formed for someone with medium- to large-sized hands because of its size and dimensions, and it feels lovely in the hand. The left side and heel area of the mouse, which are its primary touchpoints, are both constructed of luxuriously rubberized material that is incredibly soft and pleasant to rest your hand on.
The left side of the mouse has a slight slope and a resting area for your thumb (it is unmistakably a right-handed mouse). The thumb rest also serves as an additional, programmable button, however, I wish it were easier to press because the pressable portion is at the base of the thumb. This button was really stiff on my everyday driver, the MX Master 3, but it’s considerably softer on the MX Master 3S, even though it’s still in the same awkward spot.
Above the thumb rest region, neatly, are the forward/back buttons, a horizontal scroll wheel, and an LED charge indicator light that only illuminates when the mouse is being charged or has low power. The scroll wheel, right and left click buttons, and a small button that can be customized but by default changes the scroll wheel’s mode are all located on top of the mouse.
The “MagSpeed” wheel allows users to choose between scrolling in the FreeSpin and Ratchet modes by adjusting the level of friction using magnets. Thus, if you wish to scroll really quickly, the wheel can become loose and provide very little resistance, enabling you to scroll at speeds greater than 1,000 lines per second. However, it will switch back to generating tactile bumps as you walk if you need accuracy. By default, the Logitech Options+ software uses a function called SmartShift to alternate between the modes dependent on the speed of the wheel rotation. In actual use, I never needed to utilize the manual toggle button because I found SmartShift, whose sensitivity can be changed in software, to be more than sufficient.
The Logitech MX Master 3S’s bottom features three smooth black stripes that assist the device slide, a power switch, the Darkfield sensor, and a button for switching between devices. More on this will be discussed below when we discuss connectivity. But flipping the mouse over to change connections is rather awkward, even though this probably won’t bother you if you mostly use the mouse with one computer at a time.
On the front of the mouse, in a recess, is a USB-C port for charging. Although the mouse can charge while connected wirelessly and isn’t strictly usable via a wired USB connection, I found that having the mouse plugged in did not make it any more difficult to maneuver the mouse around.
Performance of Logitech MX Master 3S in Terms of Productivity
Working with the Logitech MX Master 3S is a delight. It’s simple to accomplish more because of its comfortable grip, electromagnetic scroll wheel, thumb wheel, and excellent sensor. On nearly any surface, even glass, the Darkfield sensor operates without issue. Navigation was equally precise when I used it on top of a glass tablet screen as it was when I used a mousepad.
The sensor has a range of 200 to 8,000 DPI, which is double that of the MX Master 3’s 4,000 DPI. The mouse, however, defaults to 1,000 DPI (just like it did on the MX Master 3), so you must modify it in the Logi Options+ app before you actually see a difference.
According to Logitech, the goal of tripling sensor DPI is to make it easier for users of multiple monitors to move their pointers over all of the available screen space without overextending their wrists. The target market for this function should be me because I have a four-monitor setup at home. Increasing the DPI in Logi Options+ does make it simpler for me to move between my workstations, but I’m not sure that I require much more than 4,000 DPI. When I increased my DPI all the way to 8,000 or nearly there, the pointer moved too quickly for me to control without overshooting my targets. However, on my four-monitor setup, 5,000 DPI seems to be the sweet spot.
I found the MagSpeed scroll wheel to be a big comfort while I was reading or vertically browsing through lengthy spreadsheets or papers. I didn’t need to manually swap between FreeSpin and Ratchet modes by pressing the shift wheel mode button because I found the SmartShift feature to be more than suitable for doing so.
On the MX Master 3S, connectivity and Logitech Flow
The Logitech MX Master 3S, like its predecessors, can wirelessly connect to up to three devices and switch between them instantly using either the Easy-Switch button on its bottom or the Logi Flow function of the Logi Options+ app. Either Bluetooth or a Logi Bolt dongle can be used to connect. One Logi Bolt dongle, which is already pre-paired with your mouse, is provided in the box, but you can also use a dongle you purchased separately if you link it with your mouse using Options+. It’s crucial to note that you don’t require the program to pair Bluetooth devices because the app can only be used on Windows and macOS.
It should be noted that the MX Master 3S cannot be utilized with the MX Master 3 since the Unifying Receiver from Logitech, which was the dongle standard before to Bolt, is not backward compatible. Additionally, the Logi Bolt does not support devices that are backwards compatible with the Unifying Receiver. Bolt delivers better security and less latency than Unifying Receiver, especially in areas with lots of wireless devices, therefore the company has been replacing Unifying Receiver with Bolt. The transfer is still difficult if you have several Logitech products and don’t want to use numerous USB connections for them.
If you wish to use several Windows or macOS devices side by side as if they were one long desktop, the Logi Flow function is incredibly handy. On my Windows 10 desktop and my Windows 11 laptop, which I set up to the right of my monitors, I turned on Flow. I chose the devices and placed them as boxes next to one another in Options+, and then after a very quick setup process, I was able to switch computers by simply dragging my mouse pointer off of the right side of the screen.
In order to travel between the top right and bottom right monitors on my desktop, which has four monitors stacked in a 2×2 layout, I occasionally inadvertently drag my cursor onto the laptop by going off the right side of both the top monitor and the bottom monitor. I strongly advise turning on the “Hold CTRL and Move Cursor to Edge” setting, which prevents switching between devices unless the CTRL key is also depressed.
The ability to transfer the contents of the clipboard between my two PCs was perhaps the most useful feature. I could copy text or an image on the laptop and then paste it into whatever desktop software I desired. If I want to take screenshots from Windows 11 and modify them on my Windows 10 PC, this is quite helpful.
Utilize one of Logitech’s MX Mechanical keyboards (or its older, non-mechanical MX Keys keyboards) if you frequently use Flow as they may change profiles automatically with your mouse. I connected my MX Mechanical keyboard to the laptop, turned on the “Link Keyboard” option in Logi Options, and was able to glide my cursor back and forth smoothly.
You can’t use Flow and must rely on the Easy-Go button if you wish to switch to a device that can’t run Logi Options+. I found it quite aggravating since the tiny Easy-Switch button is located on the bottom of the mouse, where it is difficult to reach because I use a Raspberry Pi with Linux as part of my workflow. The Triathlon M720 and other Logitech mice, which have that button on top, address this issue, but the MX Master range hasn’t caught on to the fact that some users prefer simpler manual switching. It would be convenient if you could individually customize one of the other buttons—possibly the thumb button or Shift wheel button—to function as Easy-Switch. But you can’t, at least not right now. Additionally, it would be convenient if manually selecting the device on your MX Mechanical keyboard would also change the mouse to the same device. Unfortunately, this is not an option.
To sum up
Having a superior mouse can help you accomplish more in less time whether you’re a developer, creative professional, office worker, or student. The Logitech MX Master 3S costs $99, which is expensive but reasonable for a top-of-the-line productivity mouse given that it is comparable to the MSRPs of both its predecessor and its principal rivals—the Microsoft Precision Mouse and the Razer Pro Click, neither of which has thumb wheels or Logi Flow—both of which are thumb-wheel- and Logi Flow-free mice. Additionally, the MX Master 3S can transform the way you operate, especially if you use numerous devices, even though you can acquire an excellent wireless mouse for a lot less money.
If you already own an MX Master 3, you probably won’t want to upgrade because of the upgrades (you may even be turned off by the quiet buttons). Additionally, if you come across an MX Master 3, which Logitech says it will stop producing, at a significant discount, you should give it serious consideration. The Logitech MX Master 3S is the best wireless productivity mouse available right now, though.
