Definite buy for me! The biggest irritation with the last iteration was the soft plastic shell - great for a year, but anything longer and the plastic starts to break down. 5 years later, it's in bad need of replacement. I expect the hard plastic will survive for many years longer.
Weird. I use my Mx Master 3S Mac for many hours a day, and after five years, the softish plastic has not broken down at all that I can tell. Maybe you have a much hotter mousing hand than I do?
 
Does their software still sucks? Stopped using my MX Master 2S when they released Options+.

Is anyone using BetterMouse instead of Options+? How is it?

It’s odd how many mouse people there are. Once trackpads were available on Macs I’ve never looked back… 😉
 


Logitech today announced an updated version of its MX Master series mouse, the MX Master 4, which features haptic feedback and introduces a few other changes while remaining largely faithful to the original design.

Apart from cleaner-looking frosted buttons and a more minimalist bottom, the MX Master 4 looks very similar to the S3. The feel is, however, slightly different – the new model swaps its predecessor's soft, ribbed finish for a smooth, hard-plastic body and buttons, although there is some softer material around the right-hand side and on the surface where you rest your thumb.

The new haptic feedback delivers subtle vibrations near the thumb for scrolling, navigation, and selection. Haptics also accompany gestures and shortcuts accessed via the Actions Ring feature (now with a dedicated button under the thumb), which can be set up via Logitech's Options+ software. You also get vibrations with a low battery warning or Bluetooth pairing.

Logitech has also updated the MX Master 4's connectivity. The mouse now ships with a USB-C Bolt receiver for lower-latency wireless connections and improved security, while still supporting Bluetooth for multi-device pairing. Battery life is still claimed at up to 70 days on a full charge, and fast charging via USB-C can deliver three hours of use in just one minute.

Other improvements include quieter, more precise clicks, double the connectivity strength, and an updated MagSpeed scroll wheel that promises smoother transitions between ratchet and free-spin modes.

The MX Master 4 is available to order from Logitech's website for $119.99 in Black and Graphite Charcoal color options, with a Mac version available in White Silver and Space Black. Shipping starts early October.

Yeah, this looks nothing like that and you’ve never used the MX series have you?

It’s the mouse that no one can live without after they use it. It’s freaking fantastic.
How does MX compare to trackball models in terms of durability? I loved my Logitech Marble Mouse, as well as a similar Kensington TB-450, but the microswitches in their buttons always failed after a couple of years. Never had buttons fail that quickly in traditional mice. After that I switched to Apple's Magic Touchpad but really miss the mouse UX. Maybe I should give the new MX series a shot.
 
I borrowed my son’s MX3s for a project and was seriously impressed. Since I usually just use my MacBook, I never bothered with a mouse. But when the project required more trackpad work than keyboard input, the MX3s was miles ahead of my old Magic Mouse (honestly, almost any mouse is better than that one). Now I’ve got my own—and I’m not going back!

Absolute scam that Logitech sell a separate Mac version for the same price and literally the only difference is that they don’t include the USB-C Bolt dongle.

Sure, you can’t just buy the PC version, but undoubtedly some people will end up buying the Mac version not knowing any better.

Problem is that softer rubber material on the sides tends to get rather sticky over time.
I hate that. But you CAN get rid of it, with some elbow grease. More on that in a minute...
Sadly, still no option for left handed users. I've used the previous version at my folks house and I really like it. A model for lefties would be a sure buy for me but Logitech does not seem interested.
...and...
I dont like that we cant get a left handed option on any of these.. us left-handed people are always stuck with basic mice!
Yep. I've had to use the Logitech trackman pro, and end up replacing them after 5-7 years when cleaning no longer fixes the buttons. The trackman is no longer available, so I tried a Kensington trackball. It's actually quite good, but I can't get the software to install on Windows 11, so I just use the default settings. As a result, I don't have a "back" button, nor do I have a "forward" button. But the Kensington DOES have a scroll ring, so that's nice.
That "soft" rubber finish that turns into goo after 4 years is a curse on all appliances.
I've successfully removed the "goo" from an old Saitek joystick and throttle, and I've also removed it from a couple of USB hubs. The hardest job was removing it from my old Ableton "Push" device...the entire back of the unit (the bottom) got sticky, and it was super nasty to the point that I was just going to duct-tape the damned thing.

But I decided to make a go of it. The goo can usually be removed with one or more of these: "Goof Off", WD-40, Isopropyl Alcohol, fingernail polish remover (acetone), a rough washcloth or towel (the rougher the better), and a lot lot lot of old fashioned elbow grease. Don't mix the cleaners, but do alternate between them. Work in a well-ventilated place. And just keep rubbing, hard. Eventually, the goo comes off onto the rough towel. Micro-fiber cloths also work well, and an old toothbrush can help you get into nooks and crannies. When you're done, dry the device off with some clean towels and wash the now-gooey towel in the laundry. It won't come "clean like new", but that'll just be cosmetic. The towel or micro-fiber cloth will still be workable for another project.
Obviously the size makes it a bit love/hate and the left-handed can forget it....
Only some 10% of the population is left-handed. But we can learn. For example, I learned guitar, violin, bass, trumpet, trombone, and more the traditional way. And now I can draw and paint with both hands. I'm equally as good with both hands at the gun range, and if I was going to do archery, I'd feel no need to do it left-handed. Same with batting and playing tennis.

I'm just more comfortable with my left hand on a trackball. But if I really REALLY had to, I could probably learn to use my right hand. It would just take me probably a good solid year.
...Hopefully they also improved the quality of the rubberized surfaces so they don’t start disintegrating themselves after 2~3 years of intensive use...
The "rubberized surfaces" are still bad, and I just wish manufacturers didn't use them. That nasty stuff has to be sprayed on in the first place, and the consumer never knows just how bad it's going to be until they've already owned that device for 2, 3, or 4 full years. And by then, it's kind of too late to raise a ruckus with the manufacturer.
It’s odd how many mouse people there are. Once trackpads were available on Macs I’ve never looked back… 😉
For some people, it's not a binary choice. To avoid carpal tunnel syndrome or other repetitive motion conditions, you have to do different things on a regular basis. So trackpad for a bit, then mouse for a bit. Mouse for a bit, then switch to a trackball...or maybe a stylus. Even the old "rubber eraser" joystick on older laptops was a good option, but only if you switched it off regularly.

I have different UI devices on my computers, so that I don't keep punishing my hands and wrists with the exact same (and same-sized) devices all the day long.

Good to see this one. Not in requirement of a new mouse immediately but will definitely keep this in mind the next time I purchase one.

Never buying Logitech ever again. Every mouse I've had from them manufactured after 2015 has sooner or later started doubleclicking including Master 3S. The new Master 4 has the same laughable specs and the same cheap parts that will degrade in 2-3 years. Only a fool with too much money would buy this.

I had the same issue with MX Vertical, double clicking. They mention it will last longer and focussing on interior materials. What I want to have is more robust buttons. But sadly there's no alternative so I just bought another one. It's like disposable technology, very sad but what can you do.
 
I have mx master 3s. In mx master 4 bigger?

A bit...

Below is from the Engadget review I linked earlier.

It is a touch heavier (150 grams vs. 141g), wider (3.48 inches vs 3.32 in.) and taller (5.05 inches vs. 4.92 in.) than the last model, but if you found the 3S or older MX Master 3 comfortable, you should have few issues here.
