Logitech MX Master 3S Review: 2026 Honest Assessment

Is the Logitech MX Master 3S Actually Worth $100, or Is It All Marketing?

Look, I am a barber. I spend 10 hours a day on my feet fading hair, managing my shop, and dealing with clients. But I also run a business.

That means when the clippers turn off, I spend another three hours staring at booking software, inventory spreadsheets, and payroll systems. My hands are my livelihood. If my wrist hurts, I cannot cut hair, and I cannot pay my rent.

So when every tech influencer on the internet started hyping up the Logitech MX Master 3S as the ultimate productivity tool, I was instantly skeptical. I do not trust people who get free products in exchange for reading a spec sheet on camera.

I bought this mouse with my own money. I have used it heavily for the last 14 months to see if it actually delivers, or if it is just another overpriced desk accessory designed to look good on Instagram.

If you are looking for an honest logitech mx master 3s review, you are in the right place. I am going to tear apart the marketing hype and tell you exactly what you are paying for.

What Logitech Wants You to Believe

Logitech has a massive marketing budget. They throw around terms like "mag-speed scrolling" and "8000 DPI tracking" to justify a $100 price tag. Let us look at what they claim versus reality.

First up is the 8000 DPI sensor. Logitech claims this allows you to track flawlessly on any surface, including glass. The marketing team won't mention this, but 8000 DPI is completely useless for 99% of people.

Unless you are running triple 4K monitors or an 8K display, setting your mouse to 8000 DPI will make your cursor fly across the screen so fast you cannot even see it. Most professionals keep their mouse between 800 and 1600 DPI. You are paying for sensor capability you will never use.

Then there is the "Quiet Clicks" feature. Logitech boasts that the 3S is 90% quieter than the older MX Master 3. This part is actually true. The clicks are dead silent.

Here's the thing nobody tells you: making the clicks quiet ruined the physical feedback. The tactile, satisfying "click" of a premium mouse is gone. Pressing the primary buttons on the 3S feels like pushing your finger into a damp kitchen sponge.

Logitech also claims a 70-day battery life on a single charge. If you leave the mouse sitting on your desk doing nothing, sure. But if you actually work an 8-hour shift, clicking and scrolling constantly, expect to plug this thing in every 40 to 45 days.

They also hype up the USB-C quick charging, claiming one minute of charge gives you three hours of use. This is accurate, but the charging port is located at the front of the mouse.

This means when you plug it in, it suddenly becomes a wired mouse. It is functional, unlike the disastrous Apple Magic Mouse that charges from the bottom, but the included cable is stiff and dragging it around feels awful.

What 500+ Real Buyers Actually Say

I scrape through hundreds of Reddit threads to see what real office workers are saying. Half the time, they are just venting about their toxic jobs. I saw one guy complaining his power-tripping boss schedules meetings right at 12:00 PM to ruin his lunch.

Another poor guy accidentally received the master salary spreadsheet and found out he makes $15,000 less than a newly hired coworker. I even saw a thread where a guy was hired, only to be told afterward about a strict no-visible-tattoos policy.

As a heavily tattooed barber, that last one makes my blood boil. But here is what all these frustrated corporate workers have in common: they are exactly the target demographic Logitech is trying to sell this $100 piece of plastic to.

When you filter out the corporate misery and look at the actual hardware feedback, a very clear pattern emerges. Real users love the shape, but they despise the software.

Logi Options+ is the software required to customize the buttons on the MX Master 3S. Users consistently report that this software is a bloated mess. It routinely consumes up to 500MB of RAM running in the background.

Mac users are particularly furious. If you look at the Apple subreddits, you will find hundreds of complaints about Bluetooth stuttering. The mouse will randomly lag or disconnect from MacBooks, forcing users to buy a separate USB-A to USB-C dongle just to use the included Logi Bolt receiver.

Then there is the longevity issue. Buyers who have owned the mouse for over a year all report the exact same physical degradation. The grey model discolors within three months, turning a gross, yellowish-brown where your thumb rests.

Even on the black model, the soft-touch rubber coating eventually breaks down. Due to the oils in human skin, the rubber turns into a sticky, peeling mess after roughly 14 to 18 months of daily use. You cannot replace the shell.

Users also praise the MagSpeed scroll wheel. This is the one feature where the reality matches the hype. The electromagnet in the wheel allows you to scroll through 1,000 lines of a spreadsheet in exactly one second.

When you spin it hard, the magnet disengages, and the wheel spins freely on ball bearings. It is mechanically brilliant. But again, users note that if you eat at your desk, dust and crumbs easily get trapped in the wheel housing, requiring compressed air to clean.

The Dealbreakers Nobody Mentions

If you are spending $100 on a pointing device, you deserve to know its fatal flaws. Let us talk about the polling rate. The MX Master 3S has a polling rate of exactly 125Hz.

Polling rate is how many times per second the mouse reports its position to the computer. A standard $30 gaming mouse from five years ago has a polling rate of 1000Hz. At 125Hz, the MX Master 3S feels sluggish on high-refresh-rate monitors.

If you have a 144Hz or 240Hz monitor, dragging windows around with this mouse will look choppy. It is completely unacceptable for a flagship device in 2024 to have a polling rate from 2012.

Next is the weight. The MX Master 3S weighs exactly 141 grams. To put that in perspective, a modern lightweight productivity mouse weighs around 60 to 75 grams. The 3S is a literal brick.

If you are an arm-aimer or someone who physically lifts their mouse to reposition it frequently, this weight will cause severe fatigue in your wrist and forearm. It is designed to be planted on the desk and moved with high sensitivity.

We also need to discuss the gesture button. Hidden in the thumb rest is a small button you can press while moving the mouse to trigger specific actions, like switching virtual desktops. It sounds great on paper.

In reality, this button is notorious for getting physically stuck. When the gesture button jams under the rubber housing, the mouse essentially freezes. You have to aggressively massage the thumb rest to pop the switch back into place.

Finally, there is no onboard memory. If you spend an hour setting up custom app profiles in Logi Options+ for Photoshop, Premiere, and Excel, those settings live on your computer, not the mouse.

If you take the mouse to a different laptop, or if you use it on a locked-down work computer where you cannot install third-party software, all your custom buttons revert to their useless default settings.

Who Should Actually Buy This

Despite my harsh criticisms, this mouse is not garbage. It is just highly specialized. If you fit into a very specific demographic, this heavy, expensive piece of hardware will actually save you time.

You should buy the MX Master 3S if you spend your entire day navigating horizontal timelines. Video editors using Premiere Pro or Final Cut, and audio engineers using Logic or Pro Tools, will massively benefit from the dedicated horizontal thumb wheel.

It is also built for spreadsheet jockeys. If you are staring at massive Excel grids, the ability to flick the MagSpeed wheel and instantly jump 500 rows down, then use the thumb wheel to pan right, is incredibly efficient.

You need to have medium to large hands to use this device comfortably. The mouse measures 124.9mm long and 51mm high. If your hands are smaller than 17.5cm from wrist to fingertip, you will not be able to reach the forward side button without shifting your entire grip.

Do not buy this if you play video games. The 141-gram weight, combined with the miserable 125Hz polling rate and heavy sensor latency, makes it impossible to use in any competitive shooter. You will lose every gunfight.

Do not buy this if you have a strict IT department. If your company blocks you from installing Logi Options+, you are paying $100 for a basic point-and-click mouse with extra buttons you cannot program.

Better Alternatives?

Before you drop a hundred bucks on Logitech's flagship, you need to look at the competition. There are mice on the market that solve the exact problems the 3S ignores.

The Razer Pro Click is the direct competitor. Razer partnered with Humanscale to design the ergonomics, and frankly, it feels better in the hand than the Logitech. It also boasts a 1000Hz polling rate, making it significantly smoother on modern monitors.

The Keychron M6 is the budget underdog. It completely rips off the MX Master shape, but it weighs only 78 grams. It gives you an infinite scroll wheel and a thumb wheel for half the price, though the build quality feels noticeably cheaper.

Here is exactly how they stack up against each other:

If you already own the older MX Master 3, do not upgrade. The 3S is identical in shape and function. The only differences are the mushy quiet clicks and the useless 8000 DPI sensor. Save your money.

Final Verdict

The Logitech MX Master 3S gets a solid 7.2 out of 10 from me. It is a legendary shape wrapped in questionable design choices and backed by aggressive marketing.

The magnetic scroll wheel is a mechanical masterpiece, and the horizontal thumb wheel is a necessity for creative professionals. The ergonomic tilt genuinely reduces wrist pronation during long office shifts.

But Logitech needs to be held accountable for shipping a $100 mouse with a 125Hz polling rate in 2024. The software is bloated, the rubber coating will inevitably degrade, and the clicks feel terribly mushy.

If your job requires heavy horizontal scrolling and you have the desk space to plant your wrist, buy it. If you want a lightweight, snappy mouse that transitions from spreadsheets to gaming, look elsewhere.
