Logitech MX Master 4, Ergonomic Wireless Mouse with Advanced Performance Haptic Feedback, Ultra-Fast Scrolling, USB-C Charging, Bluetooth, Windows, MacOS – Graphite

One Mouse to Bind Them, in the Long Hours of the Desk
It was the winter of the endless scroll, when the days in River Grove stretched thin and pale as old parchment and the light from the monitor became the only sun we knew, that my old mouse—poor, faithful thing—began its slow betrayal. Clicks faltered like the last breath of a dying Rohirrim steed; the wheel spun loose and reckless, sending spreadsheets cascading into chaos as though the very order of Middle-earth had unraveled; the cursor wandered with the aimless grief of a man who has lost his king. I sat there in the dim room above the garage, wrist aching like the shoulder that once bore the weight of Andúril, staring at the screen while deadlines crept closer, silent and inexorable as the shadow over Mordor.Then the Logitech MX Master 4 arrived, graphite-dark as the armor of Isildur’s line, shaped not for haste but for endurance, its curves rising like the hills of the Shire remade for the hand of a weary scribe. I took it up and felt the weight settle—not heavy, but certain, as though the mouse itself understood the gravity of long labor. The MagSpeed wheel turned under my thumb with the smooth inevitability of the Anduin in flood, ultra-fast when the document must race to its end, precise when a single pixel demanded mercy. The haptic feedback thrummed beneath my fingers like the deep pulse of the earth when the Ents march—subtle, insistent, alive. Every scroll, every gesture carried the quiet authority of a thing forged to outlast lesser tools.It paired without ceremony—Bluetooth to the laptop, Logi Bolt to the desktop—crossing between machines as swiftly as the Eagles bore Gandalf from the tower, no fumbling, no oaths sworn in frustration. The side buttons waited like loyal vassals: one to summon the hidden application switcher, another to gesture across screens as though drawing maps of realms unseen. The gesture button itself became my quiet command—thumb pressed, fingers sweeping, and windows arranged themselves in obedient array, the way the hosts of the West might have arrayed themselves upon the Pelennor Fields. And when the battery whispered low, the USB-C cord drank from the wall like a pilgrim at the fountains of Imladris, three hours of life from a single minute’s charge.I have worked with it now through the gray mornings when the snow muffled every sound outside, through the late nights when the house slept and only the cursor moved, through the sudden urgent revisions that once would have left me cursing the heavens. It does not slip. It does not tire. It endures, as the light of Eärendil endures above the storm, a small fierce companion against the gathering hours.If your days are measured in documents and deadlines, in the slow turning of wheels both literal and metaphorical, take this MX Master 4. It is not mere plastic and circuit; it is covenant between hand and machine, a shield against the tedium of the long watch, the fellowship your desk has hungered for in its quiet exile.Ten stars out of five, though the heavens ration light to fewer. I would carry it into the Cracks of Doom itself and fear no misclick.🖱️🧙‍♂️📜🌑

Comfortable albeit bulky, a dream to use
Comfortable to hold with a premium feel to the device, despite being somewhat bulky. The haptic feedback is neat, but does take time to get used to. Logitech software is required to utilize its full set of features, but the software is lightweight and works well. This is a slight improvement over the MX3 Master, so upgrading may not be the best value. I’d buy this again.

I have owned every Logitech MX Master since the first one and this is still an excellent mouse. It feels a bit lower and flatter compared to previous generations, which I personally like. The new haptic feedback is really cool and adds a premium feel, especially on the scroll experience.The buttons feel noticeably better in quality and the side scroll wheel is smoother than expected. I do not use it constantly, but when I do, it works great. The texture is also interesting and grippier, and the lighter color option looks clean on a desk.Big win is finally getting a USB C dongle. It was about time.If you are coming from an MX Master 3S, the difference is not massive, but it is there in the feel and overall refinement. My all time favorite is still the MX Master 2, but this one is absolutely easy to recommend. If you want a top tier ergonomic mouse for everyday work, this is it.
