Everything about the Yukon Grizzly Locker is hardcore, its casing and gears, its advanced gear tooth design, and its impact on traction and performance. The Yukon Grizzly Locker is a mechanical positive-locking differential that’s engineered for rock crawling, serious trail running, off-road racing, and drag racing. The unit provides 100% power to both tires, while still allowing for disengagement while negotiating turns. The Yukon Grizzly Locker is a patented design that features innovations that make it tougher than the competition. Its inner clutch teeth have a larger radius at the base, which offers up to 350% greater strength versus back-cut designs. The Grizzly Locker’s larger teeth also resist breakage caused by shock-loading or catastrophic axle failure. It’s a serious piece of mechanical engineering for serious driving conditions.This Part Fits:

Great mouse, but not a huge leap from previous MX Masters
Color: Pale Gray, Pattern Name: Mouse
I’ve used pretty much every mouse in the MX Master series over the years, so I had a good idea of what to expect going into this—and overall, it’s still a really solid mouse.
The ergonomics are excellent, just like the previous versions. It fits the hand really naturally and is comfortable for long work sessions. That’s honestly one of the biggest reasons I keep coming back to this lineup.
The scroll wheel is still a standout feature. The ultra-fast scrolling is incredibly smooth and makes a big difference when you’re going through long documents or web pages. Switching between free spin and precision scrolling works flawlessly.
Build quality is top-notch as expected. Everything feels premium, from the materials to the button clicks. No complaints there at all.
That said, if you’ve already used previous MX Master models, this doesn’t feel like a major upgrade. It’s more of a refinement than anything new or groundbreaking. It does everything well—but it doesn’t necessarily wow you if you’re coming from something like the MX Master 3 or 3S.
Overall, still a great mouse and easy to recommend—especially if you’re new to the MX Master series. But if you already have a recent model, just know this is more of an incremental improvement than a big jump.

Quality materials, great mouse
Color: Graphite, Pattern Name: Mouse
I have gone through many mice looking for one that feels 'just right'. This is it. The shape is perfect for my hand, the haptic feedback is nice, if not very useful to me, and the smoothness with which it moves across my pad is well worth the price alone. Nicely configurable in the Logi app.
One note - It's fine for me, but this is a very large mouse.

One Mouse to Bind Them, in the Long Hours of the Desk
Color: Graphite, Pattern Name: Mouse
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.

Almost Perfect
Color: Graphite, Pattern Name: Mouse
If you are looking for a quiet mouse, this is it. I was skeptical about the "ergonomics" but find that it is much more comfortable for me than the more traditional design for left and right clicking. Simple moving seems fine but its weight is a bit excessive for lifting for repositioning in tight spaces. It is difficult to lift without activating the button on the haptic pad, even set to require firm pressure. A bit more contour on the right would solve this nicely to allow lifting the mouse without repositioning your hand.
The forward and back buttons may be a bit awkward for some people. I'm slowly adjusting. Actually, each mouse I've owned needed a bit of getting used to. Side scrolling doesn't always work as it seems it would. Frequently, it scrolls vertically like the "normal" scroll wheel depending on the program.
Haptic feedback is not a commonly used feature yet, however, Windows will be slowly adding haptic features to later updates from what I've read. I keep the setting on the lowest haptic feedback level and for what it functions on so far seems natural and not intrusive.
There are many adjustments and customizations, too many to go into since I haven't played around with most. So far, even with what may seem like a lot of negative thoughts, I love this mouse. It would be five stars if lifting to repositioning in tight spaces was easier.

As advertised. Logitech, best mouse for your hard-earned cheddar!
It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse.
So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it!
