Writing this review after using it for a month now: Connectivity is noticeably more stable via the Logi Bolt receiver compared to Bluetooth, with consistent performance and no observable input lag during extended usage. Customization through Logi Options+ unlocks the true potential of the MX 4, offering extensive button mapping and application specific controls that significantly improve workflow efficiency. What really stands out is the high-accuracy optical sensor with adjustable DPI (up to 8,000 DPI). It provides precise and controlled cursor movement, making it well suited for long hours of technical work such as software development. The ergonomic design helps reduce fatigue during extended coding sessions after using for more than 2 weeks. The MagSpeed scroll wheel adds substantial value, especially when navigating large datasets, long code files, or massive drum arrangements during music production. The seamless transition between precision scrolling and free spin mode makes timeline navigation fast and effortless. After using it for more than 4 weeks, the only downside is the weight of the MX 4, which may feel slightly heavy for users who prefer lighter mice or make frequent, rapid movements. However, this trade-off also contributes to its premium build and stability.

I switched from the Razer Basilisk V3 Pro to this mouse looking for an ergonomic improvement to reduce wrist fatigue and this mouse does not disappoint, the addition of the side scroll button and the haptic button have been a game changer for me in terms of productivity and saving time during work hours. The battery is a huge jump compared to the Basilisk's battery (taking into account that this mouse does not have RGB like the Basilisk) if what you are looking for is to optimize your productivity and more importantly take care of the health of your wrist, this is the way to go.

Best mouse I’ve ever used. The battery lasts forever and the bluetooth connection is strong

Love it. Lightweight premium feel truly works on glass and whatever other surface you might use it on, they say it’s more of an at home desktop but with a carrying case it is just as effective on the go as at home

Excellent ergonomic mouse. It is worth it, and fun to use

Great mouse for work. Do not try to game with it, but it’s great for productivity

Love this mouse. The haptic and silent clicks are amazing. My new go to for work projects

I’ve used a lot of mice over the years, and the Logitech MX Master 4 Wireless (Pale Gray) is easily one of the most refined ones I’ve had on my desk. First off — the comfort is real. It fits naturally in my hand, especially with a palm grip, and I can use it all day without feeling wrist fatigue. The shape and thumb rest make it feel intentional, not generic. It’s clearly designed for people who sit at a desk for long hours. The scroll wheel is probably my favorite feature. The MagSpeed scrolling is insanely smooth. I can switch from precise line-by-line scrolling to flying through long documents in seconds. If you work in spreadsheets, dashboards, long PDFs, or code — this makes a noticeable difference. The customization is where it really shines. Multiple programmable buttons, the thumb wheel, gestures — once I mapped them to my workflow, it actually saved me time. It’s not just extra buttons for the sake of it. If you’re willing to set it up properly in Logi Options+, it becomes a productivity tool, not just a mouse. The haptic feedback is subtle but interesting. It gives a small tactile response when triggering certain actions. It’s not life-changing, but it does make interactions feel more premium and deliberate. Battery life has been solid. I don’t think about charging it often, and USB-C fast charging is convenient. The wireless connection is stable whether I’m using Bluetooth or the receiver. A few honest notes: It’s not small. If you have smaller hands, it may feel bulky. It’s right-hand only. To unlock its full power, you do need the Logitech software running. Overall, this feels like a serious desk setup mouse — not something you throw in a backpack for coffee shop work. If you spend hours a day working on a computer and care about efficiency and comfort, it’s worth it. If you just need something basic for casual browsing, this is probably more than you need. For me, it’s a long-term productivity upgrade, not just another accessory.

Was kinda concerned about this mouse at first. I mostly game and I know this more of a productivity mouse but this mouse is still great for gaming, maybe not professionally but as a casual gamer I love it. I have been getting annoyed by RGB everything recently and that's one of the things I love about this mouse. It's also very comfortable to use. The haptics are a nice touch. I love the customizability of the action ring. You can do so much with it. I really like this mouse. I bought this one as a gift for my gf and liked it so much I ended up buying one for myself too.

The MX Master 4 has quickly become an essential part of my daily setup. The ergonomic design is incredibly comfortable for long work sessions, and the wireless performance is rock-solid. The haptic feedback on the scroll wheel is a game-changer — it adapts intelligently depending on what you're doing. Battery life is excellent, and the pale gray colorway looks sleek. If you spend a lot of time at a computer, this mouse is absolutely worth the investment.

I’m really impressed with both Best Buy and the MX Master 4. Best Buy shipped my order fast, the checkout process was simple, and the product page had plenty of reviews and details to help me feel confident about the purchase. As for the MX Master 4, it’s easily one of the best mice I’ve ever used. It’s super comfortable, the new haptic feedback feels great, and the quick-select button is a smart upgrade. Putting my Mac and Windows laptops to sleep is instant and effortless. The slim USB receiver is also a nice touch. My only wish is that the mouse had a built-in spot to store the receiver when I’m traveling, since I use it with my laptop and prefer it over a trackpad. Overall, I’m really happy with it and would definitely recommend it.

The battery life is insanely good, I can adjust the controls to how I want them, and it connects almost instantly to my computer. Highly recommend in general, but mainly anyone who needs to mouse for editing softwares like DaVinci Resolve or After Effects.

I was looking for a mouse that would (a) be gentle on my hand, (b) offer precise movement, and (c) switch easily between multiple devices. After reading through several options and talking with the store associate, I decided on the Logitech MX Master 4. I’m very happy with my purchase so far—it's comfortable, accurate, and effortlessly connects to all my devices.

This mouse offers a remarkably quiet clicking experience, which is a true pleasure during extended use. The ability to connect via both a convenient USB dongle and seamless Bluetooth is a fantastic feature. It provides excellent flexibility for switching between different devices and environments. I have found the performance to be consistently reliable and precise. Overall, this mouse is a wonderful choice for anyone prioritizing a peaceful and versatile computing experience.

Love this mouse. Works much better than the Apple mouse that came with my iMac. I did learn that you don’t need to get the Mac version mouse. The regular one works great. You just need to use it with the supplied dongle which ultimately makes it work faster as well from what I read.

First ever mouse I dropped a good amount of money on. At first I was skeptical but once I used it for a while, I ended up loving it. The vibrations and the grip feel amazing and the buttons make having shortcuts easier.

This is such a comfortable mouse easy to use and lots of buttons to customize. This is my 3rd one each one a newer version. I use all three just keep them in different locations.

I'm still getting used to the mouse but it fits my hand great and has great features that helps me navigate better than my previous trackball. I purchased this to replace the trackball and had to be ergonomic to help with carpal issues. So far so good

The mouse is awesome and fits my hand perfectly. Its also quite good for gaming
