Logitech MX Master 3S

The first MX Master 3S I had lasted a bit over 3 years. The battery would be constantly needing to be refreshed about once a week. It kinda got annoying. I still have it with the intentions of hacking it and replacing the battery for a secondary mouse for use in the garage, but ... I'm trying to get other things done first.

I bought a Logitech trackball (the MX5something), and the switches stopped working a year in. Amazon refunded me, so I bought an MX Master 3S. The switches for that also stopped working a year in. I complained to the merchant and Logitech, and luckily they sent me a new mouse each. I also bought some replacement switches and repaired the lot, so now I have four mouses/trackballs. Still, they should make better mouses.

I had two mouses get that problem about a year in. One was the MX Master 3S, a 100 € mouse. For that price point, it's entirely unacceptable for the mouse to only last a year. Good thing it had a two year warranty, but it's such a hassle to be without a mouse for weeks.

I have a Iiyama with build in hub, at first it seemed ideal, just plug everything into the monitor. But my mouse glitches when used through the hub (MX Master 3S), the internet cable is only available to the active computer (so no tasks requiring internet can run on the other computer). All in all, I just use the USB-C to HDMI switch functionality and couple the computers to keyboard/mouse via bluetooth, plus I bought a switch for the ethernet. It's a shame it's so suboptimal. Another minor annoyance is that when I turn off one computer and want to switch to the other, the display turns off, taking about 5-10 sec to do so. Then I manually turn it back on and it's ready in another 3 sec. So I do this thing where I hover about the turn-off button, hit it and immediately switch so the monitor won't turn off. It's hard to make convenient tech it seems.

> Connection Bluetooth (USB receiver also works for basic buttons) Why is there a difference between the two? On my MX Master 3S, I find the scroll wheel is… weird on Linux if I connect it via BT. It works fine with its dongle. Why does the transport have such an effect on what seem like HID functions?

My first MX Master 3S had a bad right or left click button on Day 1, which would miss clicks constantly. Thankfully it was pretty easy to get a warranty replacement for this, which came as a full retail-boxed unit, so I now have an extra receiver too (I understandably had to mail in the useless defective mouse itself).

I love the MX vertical's ergonomics, it's really the perfect mouse for me in that regard. It just feels... right. But I'm sad that the mouse is absolutely miles away from the MX Master mice in terms of quality and features. I developed serious wrist/hand pains after switching to the MX Master 3S for a few months, but its magnetic scroll wheel and build quality was absolutely glorious. The MX vertical is a plastic toy in comparison, but it costs the same.

I can relate in so many ways. I purchased a MX Master 3S and while it has a lot of great design choices, overall there were too many flaws for me and I returned it. While I had the mouse, I kept looking for ways to "fix scrolling" and everything repeatedly pointed to third party software. If you have an iPad or Android device, you're completely out of luck. How does a company become so out of tune with customers that customers feel the need to "fix" the design flaws of devices they bought? I'm not one of those people to "fix" the device, because when I found the polling speed and latency couldn't be increased, that was a complete stopper for me. I really wanted to make the mouse work for me, I really tried to make it work, but I couldn't get past the many flaws. It felt as if they went backwards from their old devices like the MX Revolution in many ways.

I’m also going to return an MX Master 3S (to my employer though). I could only fix its weird scrolling behavior with Logitech’s bloatware, still, for the life of me I couldn’t improve the cursor precision on macOS, it’s was simply maddening to use it. Strangely on Linux the precision issue isn’t so bad.

I see a number of recommendations for Logitech mice, FWIW I got a MX Master 3S because I once had a MX Revolution that I loved. Well, I hated it and returned it. The polling speed was awful, Bluetooth connectivity laggy, no built in settings memory, it doesn't scroll correctly with anything Apple out of the box, and there's no mobile apps for it if you want to expand beyond desktop operating systems. I ended up sticking with what I already have, but if I were to go and buy something today it would be a Razer Basilisk V3 Pro or a Magic Trackpad.

Yea, somewhat disappointing. My mx 3s mouse has problems with the click switches and the mouse isn’t all that old. I’ve also read about others with the problem. I would also like to be able to buy a replacement case for when the rubber starts to come apart. Has not happened on this mouse yet but on all other rubberized mice I’ve had. Replacement key caps for my keyboards would also be nice.

I think the real highlight is that it is not backwards compatible. So I now have an MX Keys and an MX Master 3s, both on their own dongle.

Logitech G mice dont need the app, but regular ones do. My Mx master 3s and Mx ergo reset to the default sensitivity and button functions if I leave them alone for a while.

Yes, this is the method that I have been always using. But I have had many cases where it seems to reset or bug out in some other way, and the Logitech MX Master 3S does still does not work well. There's definitely something weird about movement, it doesn't feel linear and accurate even after running this command. The mouse feels perfect on Windows/Linux, but it's off in my Macbook. Sometimes also loses bluetooth connectivity, where it kind of starts to skip and/or stops working completely. And I have to take the bluetooth usb, put it back in for it to work normally again. Maybe I should try another mouse, if you have any recommendations for a similar, ergonomic wireless one. Definitely don't want the magic mouse. Ergonomically I think the Logitech one is perfect for me.

Mine has worked flawlessly for about a year. A few months ago, it’s become horribly janky and I can’t figure out why. Tried different MX Master 3S units and different computers in different rooms but it’s just janky everywhere now. (Bluetooth keyboards, too.)
