Pros
- Haptic feedback on actions, shortcuts, and notifications enhances workflow engagement.
- Actions Ring provides a customizable overlay for app-specific tools, potentially saving up to 33% of time.
- MagSpeed scroll wheel allows for ultra-fast scrolling (1,000 lines per second) and precise pixel-level stopping.
- New silicone and hard plastic materials on the sides are easier to clean and more durable than previous rubber coatings.
- Quiet Clicks reduce noise by 90% while maintaining a tactile feel.
- 8,000 DPI optical sensor tracks on various surfaces, including glass.
Cons
- Weighing 10.2 ounces, it's heavier than its predecessor and some users find it less comfortable for lifting or extended use.
- The 125 Hz polling rate is considered slow for gaming and can result in less smooth cursor movement on high refresh rate monitors.
- Ergonomics are perceived as worsened by some users compared to the MX Master 3S, with a less hand-filling shape and reduced grip security.
- The mouse lacks a wired mode, relying solely on Bluetooth or the USB-C Logi Bolt receiver for connectivity.
- Haptic feedback has limited application support, making it a 'hit-or-miss' feature for many users.
Dimension Scores
The 8,000 DPI optical sensor provides high precision and tracks reliably on virtually any surface, including glass.
The sculpted design is comfortable for right-handed users over long periods, but some find the 10.2-ounce weight and altered shape less hand-filling and grippy than previous models.
It offers versatile connectivity via Bluetooth and a USB-C Logi Bolt receiver, supporting up to three devices with smooth switching.
The mouse features a premium, sturdy feel with improved silicone and hard plastic materials designed for better long-term durability, though the internal switches are reportedly unchanged from the 3S.
Best For
- Professionals engaged in creative work or data analysis requiring precise control and customizable shortcuts.
- Users with multi-device setups (up to 3) who need seamless switching between Windows, macOS, or iPadOS.
- Individuals who prioritize quiet operation in shared workspaces due to 90% reduced click noise.
- Those seeking a durable mouse with materials that resist degradation from skin oils and frequent use.
Not Recommended For
- Competitive gamers due to the 125 Hz polling rate and 10.2-ounce weight.
- Left-handed users, as its sculpted design is specifically for right-hand comfort.
- Users with small hands who might find its large size and changed ergonomics less comfortable.
Watch Out For
- The 125 Hz polling rate means cursor movements may not appear as smooth or consistent on high refresh rate monitors, which can be noticeable even outside of gaming.
- Some users report the mouse feels less secure in hand compared to the MX Master 3S, attributed to the smoother plastic finish replacing the grippier rubber.
- Logi Options+ software, while offering extensive customization, requires users to log in, and some have experienced issues with plugin downloads.
- The haptic feedback, while innovative, has limited application support, leading some users to find it a 'gimmick' rather than an essential feature.
- Despite the improved materials, the mouse reportedly uses the same physical switches as the 3S, raising concerns about potential long-term button failure.

What Buyers Say
The biggest change users are talking about is the switch from the old rubberized coating to new silicone and hard plastic, which is a welcome durability upgrade, even if some miss the old grip. The haptic feedback is a mixed bag; some find it engaging for the Action Ring and notifications, while others see it as a 'gimmick' due to limited app support. The 10.2-ounce weight and 125 Hz polling rate are consistent points of contention, especially for those hoping for a lighter, faster mouse.
“Man, this thing is heavy, and the polling rate is still stuck in 2010, but those haptics are kinda cool for the Action Ring, and the new material feels way better than that gross rubber on my old MX3S. Still, why no wired mode, Logitech?!”
Common Praise
- The haptic feedback adds a new layer of engagement, particularly with the Action Ring and desktop switching.
- The MagSpeed scroll wheel's speed and precision are highly valued for navigating long documents and spreadsheets.
- The new silicone and hard plastic materials are easier to clean and feel more durable than the previous rubber coating.
- Quiet Clicks are appreciated for reducing distractions in focused work environments.
- The ability to seamlessly switch between up to three devices is a significant productivity booster.
- The improved horizontal scroll wheel is more exposed and offers greater travel, benefiting spreadsheet users.
Common Complaints
- The 10.2-ounce weight makes the mouse feel heavier and less comfortable for some users, especially when lifting it.
- The 125 Hz polling rate is a recurring disappointment, leading to less smooth cursor movement on high refresh rate displays.
- Some users find the altered ergonomics less comfortable and less hand-filling compared to the MX Master 3S.
- The lack of a wired mode is a drawback for users who prefer a wired connection for reliability or to avoid wireless interference.
- Limited application support for haptic feedback means the feature isn't fully utilized by all users.
- Concerns about the durability of the internal switches persist, as they are reportedly the same as the MX Master 3S, which had reported failure issues.
Ownership Tips
- The new silicone material on the sides holds up much better against skin oils and general grime compared to the rubberized finish of older MX Master mice.
- The utility of haptic feedback varies greatly depending on individual workflow and the specific applications used, as support is not universal.
- Battery life is genuinely long, with users reporting around 70 days of use on a single charge, reducing frequent charging needs.
- The Logi Options+ software is essential for unlocking the full customization potential, including the Action Ring and haptic settings, but can be finicky with login requirements and plugin installations.
Frequently Asked Questions
Does the MX Master 4 have a wired mode?
No, the MX Master 4 operates exclusively wirelessly, connecting via Bluetooth or the included USB-C Logi Bolt receiver.
Is the MX Master 4 suitable for gaming?
No, it is not designed for gaming. Its 125 Hz polling rate is too low for competitive play, and its 10.2-ounce weight makes it less agile than dedicated gaming mice.
How does the new material on the MX Master 4 compare to previous models?
The MX Master 4 features silicone and hard plastic on its sides, replacing the rubberized coating of the MX Master 3S. Users report this new material is easier to clean and more durable, though some find it less grippy initially.
Can the haptic feedback be customized or turned off?
Yes, the haptic feedback is customizable in intensity and can be turned off entirely through the Logi Options+ software.
Does the MX Master 4 work with multiple computers?
Yes, it supports smooth device switching for up to three devices via Easy-Switch or the new Action Ring, and is compatible with Windows, macOS, Linux, ChromeOS, and iPadOS.
Buying Guide
When buying a productivity mouse like this, you need to think about how you work. Do you switch between multiple devices a lot? Do you use complex software that could benefit from customizable shortcuts? Your hand size and grip style also matter, as a mouse's shape and weight can make a big difference in comfort over an 8-hour workday. Don't just look at features; consider how they integrate into your actual daily tasks.
DPI (Dots Per Inch)
This tells you how sensitive the mouse sensor is. A higher DPI means the cursor moves further on screen with less physical mouse movement. For a large monitor or multi-monitor setup, a high DPI like 8000 means you don't have to drag your mouse across your entire desk to get from one side of the screen to the other.
Polling Rate (Hz)
This is how many times per second the mouse reports its position to your computer. A 125 Hz polling rate means it reports 125 times a second. For basic tasks, it's fine, but on a high refresh rate monitor (like 120Hz or 144Hz), a low polling rate can make the cursor feel less smooth or responsive, almost like it's skipping frames.
Haptic Feedback
This is a fancy way of saying the mouse vibrates to give you tactile cues. It's like your phone vibrating for a notification. On this mouse, it can confirm actions, shortcuts, or even tell you when you've switched desktops, adding a physical 'feel' to digital interactions.
Alternatives
If this mouse doesn't quite fit, look for models with a lighter weight (under 4 ounces) and a higher polling rate (1000 Hz or more) if gaming is a priority, or a more neutral, ambidextrous shape if you're left-handed or have smaller hands.
