Logitech - MX Master 4 - Adobe Edition - Wireless Laser Ergonomic Mouse with Advanced Performance Haptic Feedback - Wireless - Black

[Employee of bestbuy] Considering the price increase from $99, the MX Master 4 mouse had some pretty big shoes to fill coming from the 3s series. As my favorite mouse for many years now, the simplicity, ease of use, and premium materials warranted my purchase, with this mouse being no exception. ***PROS*** + Out of the box, the Master 4 mimics the silhouette of the Master series as a whole, exemplifying the ergonomic- and productivity-focused design seen its predecessors. Making the horizontal scroll wheel larger and moving it up the ridge of the device allows for a >180 degree range of motion, thus allowing the 4 to surpass the 3s and its recessed nature. + The 4 implements an intuitive haptics system* (<-see cons) that connects the user to the interface, buzzing when pairing the device, moving between windows, and using the newly integrated actions ring, allowing the user to access apps and actions with the click of a button. + Fixes issues with clunks, vibrations, and "stickiness" associated with the 3s and its scroll wheel, an issue that drove me crazy. (Specifically when I stopped scrolling and the magnet would click back in, along with a loud clunk.) +Improved click noise, incorporated smoother scrolling, and solidified the metal vertical scroll wheel to mitigate horizontal movement/play. + Switched the main body from (notoriously fragile) soft-touch rubber to a textured high-quality plastic, helping with sweat buildup and the ability to keep the mouse clean. Surprisingly comfortable considering how much I loved the material for the 3s. + Moved the tab-switching button from the thumb joint (sometimes awkward for smaller hands) to the actual thumb, along with an EXTRA programmable button for preferential customization. + USB-C dongle for Logi is always a plus. Going in the right direction with their compatibility. +Screw holes allow serviceability & right to repair ***CONS*** (-1.25⭐) - (*<-From before) Logi Options+ MUST be installed to use the haptics on the mouse in a meaningful way. There is NO on-board memory. Users working in a company that blocks 3rd party software LOOK ELSEWHERE, or, get the 3s. Thank goodness the software is free. (-.5) - Standard 125 Hz polling rate. This is an outdated and honestly confusing omission from this mouse, regardless of its "work and productivity" niche. This makes using the mouse on 120Hz+ monitors a drag, with the mouse "catching up" to the display. Considering you can purchase a productivity-based mouse with a 8000Hz polling rate for $70, this is a terrible look for Logitech. They are lucky the majority of monitors and computers are only 60Hz, including mine. (-.5) - On the 3s, there was a small solid plastic lip that allowed my ring finger to rest but not interfere with the mouse. Due to the refreshed design, I need to rest that finger on the right-click button, alongside my middle finger. This leads to misclicks but will be something to get used to. (-.25) CONCLUSION: Overall, this is a thoughtfully designed, well built, and multifaceted mouse. I will be keeping it, however, my 3s is on standby due to the software limitations of the 4's full functionality. 4 ⭐ because the haptics are cool (+.25), and 3.75 doesn't exist for Best Buy reviews.

Using the Logitech MX Master 4 every day has genuinely changed how I work at my desk; it feels like the kind of mouse you stop noticing because everything just flows a bit smoother. The shape is really comfortable for long sessions, with a solid, slightly heavy feel that keeps my hand relaxed instead of clawed, and the thumb rest plus extra buttons are actually usable rather than just being there for show. The main scroll wheel is incredibly smooth and being able to flick it into free‑spin to fly down long PDFs or spreadsheets, then go back to precise steps, makes big documents way less tedious, while the side thumb wheel is perfect for horizontal scrolling in timelines and wide sheets. What surprised me most is how much I rely on the customizable buttons and gestures now: I’ve got them mapped to switching desktops, media controls, copy/paste, and a few app‑specific shortcuts, so I reach for the keyboard a lot less. Battery life hasn’t been a worry at all—weeks go by without charging, and even when I forget and it runs low, a quick plug‑in over USB‑C during a break is enough to keep me going. It’s definitely not a competitive gaming mouse (it feels too heavy and not as snappy as esports gear), and the price stings a bit, but as a daily workhorse for productivity and creative work, it feels absolutely worth it and hard to give up once you’re used to it.

I’ve been using the Logitech MX Master 4 (Adobe Edition) for my photography and editing workflow, and it’s honestly one of the best upgrades I’ve made. The precision is on point, especially when working in Lightroom and Photoshop everything feels smooth and controlled. The customizable buttons make a huge difference. Being able to map shortcuts for editing speeds up my workflow a lot, and the horizontal scroll wheel is clutch for timelines and detailed adjustments. The ergonomic design is also perfect for long editing sessions no hand fatigue at all. Battery life is solid, and the wireless connection is reliable with no lag. Overall, if you’re a creative, photographer, or editor, this mouse is definitely worth it.

I honestly don’t understand how I lived without this mouse before. It completely changed my setup. The app that comes with it is amazing , you can pair it with your laptop and easily share files and photos between devices. It’s also super quiet, which makes a huge difference. Definitely worth it if you spend long hours working on your computer.

The Logitech MX Master 4 Adobe Edition is an amazing mouse and has completely changed the way I work. The ergonomic shape feels perfect in the hand, the new haptic feedback is surprisingly useful, and the MagSpeed scroll wheel is insanely smooth. The 8K DPI sensor is super accurate, and the customization through Logi Options+ makes it even better for creative apps. I’ve used a lot of mice over the years, but this one stands out immediately. If you spend long hours editing, designing, or doing productivity work, this mouse is absolutely worth it.
