The MX Master 3S uses the same wheel as MX Anywhere 3S do, which I have used for a few days already. I've chosed the Anywhere version because I do not need a horizontal scroll wheel, since I'm used to shifting for making horizontal scroll, and because of a size. The gestures are implemented better in a Mac Mouse Fix app, which works with all mice, except for Logi ones, if you have installed the app, because that one intercepts the mouse input. In fact, the gestures are not implemented good at all with Logi. It is hard to explain why exactly, but in short - they do not feel natural. Maybe because the mouse is locking a cursor position when doing gestures despite you actually moving the mouse, which causes a dissonance. In any case, after using the Anywhere 3S mouse for a few days, my impression is that It doesn't add much for me. It feels worse in gestures and scrolling compared to Apple Magic Mouse. It feels worse in gestures and scrolling compared to generic Logitech office mouse with Mac Scroll Fix app. Has less useful gestures too. The smooth scrolling option does not what you expect. It does not simulate the smooth scrolling of a Magic Mouse or Magic Trackpad. But allows for even more granular scroll between ratchet clicks, which is annoying because whatever you scroll shakes when you place your finger on a wheel. It does not do kinetic scrolling as you can do with touch gestures or Mac Scroll Fix on a regular wheel. The electromagnetic wheel can simulate this by sending a lot of by-pixel scrolls when you flick the wheel, but this is a hack, rather inconvenient. The electromagnetic wheel also does not allow for 1 line scroll per 1 ratcher click or any other number of lines, because it scrolls in pixels. This kind of scrolling cannot be changed no matter which sensitivity you set. The macOS settings for number of lines per 1 ratchet click is completely ignored. This breaks how games work with mouse wheel completely. I do one ratchet click but instead of switching to the next or previous item the game scrolls across a few of them. Every time the different amount somehow. The Logic app breaks how mice interacts with Mac Scroll Fix. Anything related to scroll does not work. And the sensitivity is kinda weird. I have been able to match it somewhat to what I get with magic mouse by setting a 450dpi value on a mouse. Which is weird, since Magic Mouse has 1300 dpi. Have no idea why this is, but in the macOS the same pointer speed is set, which is actually a multiplier for DPI. As for this moment, Anywhere 3S, which is a smaller version of MX Master 3S is underperforming for me. I feel better with a generic mouse with a descrete scroll wheel or with Magic Mouse, The only difference which made things better for me is that the wheel is physical and there is a second physical button, which Magic Mouse does not have. So yeah... Kinda not what I've expected.

Purchased this for ergonomic reasons. Hand cramping with Apple mouse and charging has become annoying. Crazy because I’ve had it for like 8 years. Should’ve switched earlier.

Never realized I used 'the claw grip' :) Nice to be aware of it. I was planning on buying the MX Master 3S. Now I think I don't ... review was helpfull. thx!

Thanks for the review! Just wanted to know if the mouse felt choppy compared to the regular mac touchpad. A few weeks ago I bought my mx 3s (the regular version, not "for mac") and it felt notably slow and choppy. Apparently, it is a common issue when 3s feels laggy while connected via bluetooth to mac (like it runs on a 90hz polling rate while the screen is on 120hz). So I wanted to know if it only pertains to the regular 3s version or the "for mac" as well. Will be really grateful to hear from you!

I still have to search for the thumb button when I want to press it. Other buttons are natural. I can't decide which style of vertical scrolling I prefer.

I lost my magic mouse yesterday. The main disadvantage to it is it won't run when plugged in. My hand is small. But after finally getting it on, I tried to find out how to use the buttons. Switching between desktops is more difficult with the MX 3S. I didn't even notice the gesture button! I'm trying to find apps that use the buttons. And I haven't been able to find out the equivalent of a one-finger sliding my magic mouse over a mail preview to delete it.

Do you know if the variety which is not "for Mac" will work well with Mac too?

With the logi one, you can adjust the dpi level to the speed you want.

thanks for the video, helpful. i love mine for sure.

is it lagging on mac ? because Logi MX master 3s (without mac badge) is lagging and nothing helps to resolve this with mac m1 pro

Does it yellow? I've read several reviews recommending the Space Gray version over Pale Gray.

You're quite right regarding the non-linear cursor movement. That's one thing I haven't found anywhere else but in Apple. it's a shame they're not making ergonomic Mouses yet.

Does the Logi Options+ app continuously run in the background? I noticed many reviews saying that sometimes, the saved customisations stop working randomly, have you noticed anything like that?

If you're using a dock, or can be bothered to plug and unplug it when you move your laptop, you definitely want the dongle latency is noticably less than over bluetooth, atleast for me using a high refresh rate screen.

Hey, Ive read that the mouse has a lot of lag when used on Bluetooth, is it still very bad? have there been any updates by Logi to make it better?

Is it loud? Like the clicking action of the buttons and scroll wheel...

Is it better than apple magic mouse bit had me giggling. Any mouse is better than the magic mouse xD

Logitech supports acceleration as well.

are you getting any lag or jitter issues on Mac?

For me, the winner is the Magic Trackpad, bar none. I can't live without all of the gestures. The Magic Mouse has more gesture support than the Logitec mice, but it doesn't support all of them.

interesting review. i'm the opposite. there's no world where i think the apple mouse is comfortable or what i want. I' ve never been a fan. I've had third party normal mouses, i've never like swiping, i prefer actual buttons. i've always preferred buttons. so for me this sounds like exactly what i'd like. myu parents have apple mice and i've never thought it was well designed and not ergonomic. I have read get the pc version and take the dongle for less latency.

thanks for comparing between Magic mouse and this one, this is exactly what I have been trying to understand

I just wish the magic mouse didn't have sharp edges, the magic is so magic

Harrison did you really just take several hours telling us the Master 3S is a different shape to the Magic Mouse. I don't want to be mean, but I was losing the will to live there for the first few hours, and then you carried on talking about it several hours more! Woah! Did you really just say that you set sensitivity to the max to save time? Regards the Master 3S being linear, do you know about Smart Shift which you can set up and control in Options?

the apple mouse is no good i love the mx master 3s

apple magic mouse has shit ergonomics

I love this mouse, but Logitech is a horrid company. Soon after I got it, it dropped their customizable Logitech Plus software…. So now, this $100 mouse is just like any other. Because Logitech won’t update their software (it simply just crashes everytime it’s loaded), you have to buy a 3rd party software to unlock the ability to customize. Because of this, it’s a $50 mouse, at best….more people need to realize this.
