I love the Logitech hardware quality but I really wish they'd work on their software quality.

I'm using a G502 at work right now with Logitech Gaming Software and the two completely baffling decisions they made with that software on macOS:

1. It has to be running. If I launch it for configuration and hit ⌘Q it stops working and my mouse reverts to the default. I have to remember to close the window instead, which leaves it in the menubar.

2. I can't unmap buttons and have them act as generic HID mouse buttons. I can map buttons to mouse 1, 2, and 3, but I can't go past that. I can map buttons to various special functions, but it would be a hell of a lot more flexible if I could just have mouse 4 and mouse 5 mapped. For example, I can map the "sniper" button to Mission Control, but I can't change its behavior with keyboard modifiers, whereas if it was just Mouse 5 I could use the system configuration to map that to Mission Control and then use keyboard modifiers to change its behavior.

For those interested, Logitech recently resurrected [1] their most famous mouse. The MX518. At least I was able to now buy it from retailers in Europe :) I love it. Could never get used to the more bulk Logitech mice such as the one in OP.

My mouse progression since 2005 has been MX518 - G400S - G903. I used the G502 for a few days when it first came out, and couldn't stand it because it just felt...weird with my grip. It also made my hand hurt.

I'm completely locked into Logitech since I just can't function without a free-scrolling scroll wheel, and they apparently have it patented. I tried some of their other newer mice without free-scrolling, and not having it is just a complete dealbreaker.

I'm very happy with the G903 so far. The worst part was definitely the price. I'm tempted to get the new MX518, but I feel like the G903 is strictly better for my usage right now.

I've been using the 2S for a while and just bought the MX 3 because I needed an extra mouse.

They managed to improve an already near-perfect mouse. I just love the 3. Probably not worth ditching your 2S for, but nonetheless, a superb upgrade. I always felt the thumb buttons were awkward on the 2S and that has been rectified. The magnetic wheel is also really nice to use.

I just wish that MX Master 3 had a couple of extra buttons by the thumb.

My 3 thumb buttons on my Logitech G500 are mapped to: Page Up, Page Down, and Back. Clicking and holding the Page Up button can rapidly take me back to the top of a page without moving my right hand to hit the home key on my keyboard. It's pretty useful, in my opinion, to be able to roughly and quickly scroll with Page Up/Down, then fine tune with the scroll wheel.

Looks like with the MX 3, I'd lose the back button though, because I really don't like the "gesture button" they've added.

Is the thumb-wheel on the MX 3 "clickable"?

Regarding Logitech Mice, I have the Anywhere MX and the Anywhere MX 2S here. I rarely used the old AMX but still, I got a defective left button switch after about 5 years in which I used it probably less than 500 hours total. Changing the switch is needlessly cumbersome, you have to remove rubber pads and battery stickers (which can't really be removed without destroying them). But the AMX feels solid and the on/off switch also functions as a protector for the laser. You can also store the USB receiver between the batteries.

The AMX 2S is an absolute downgrade: Much cheaper build quality, no more protection for the laser, no user removable battery. The old AMX came with a leather pouch for transportation, the AMX 2S doesn't. On top of that, the Bluetooth connection of the AMX 2S is terrible. I have frequent minute long disconnects from my MBP at 20cm distance. Sometimes it won't connect at all. And the battery doesn't last as long as the rechargeable batteries I put in my AMX 1.

The scroll wheel in the Master 3 is totally broken. It doesn’t register scrolls properly. Within 10 seconds I noticed the issue. Same issue across multiple devices and OS’s too. Others have noticed too, like here: https://www.reddit.com/r/MouseReview/comments/d6yo5j/anyone_...

I returned mine and got a G604, which is a work of art, and you can load settings into on-board memory so you can delete the Logitech software after doing that.

I use the Anywhere MX 2, which is quite good, and would love to try the Master 3, but I mouse left-handed. Would love to see more support from Logitech for this mode, even if it came at a premium.

I'm really curious about the silkscreened ruler. Can anyone solve the mystery?

Does the 3rd version fix the polling issues these mice have over Bluetooth? Using the receiver works fine, but over Bluetooth it feels very laggy and jerky to use. They don't offer a USB-C receiver yet.

Here is what it looks like to draw a circle using each protocol: https://imgur.com/a/RP2oLcn

Do they make high-quality mice like these for left-handed people?

I'm always jealous by this type of mouse, while I'm stuck using my cheap sad ambidextrous Microsoft mouse.

Great mice but I’m surprised no one has mentioned weight. The master 3 is 141g! That’s a brick!

I’ve been hunting for a mouse with this kind of scroll wheel that was less than 90g or so forever. 141g would kill my arm in a few hours.

I use an MX Anywhere 2 at work and an MX Anywhere at home. I love both of them (so much that I soldered in new microswitches when the original buttons on the MX Anywhere wore out).

I have never tried an MX Master. I have been curious, but I don't need the second scroll wheel.

I think the software is somewhat convoluted. My actual preference is that Mac OS would support all of the functionality natively. I think it's stupid that we need to use extra programs to get the keyboard/mouse to do what we want.

I'm glad they changed the scroll wheel–it was arguably the worst part of the first one. I have had one for a few years, and the mechanical part that determines whether the wheel is free spinning or ratcheting has a tendency to slip over time, making the ratchet less effective until it is all gone. The mouse needs to be opened up every few months to poke the part back down. This is not an uncommon problem and I'm glad the mechanism has been changed.

I see that Logitech ramped up their advertising investment again. I looked up the mouse and it shows up on all popular youtube channels with crazy titles.

I remember same thing from the original Performance MX. Everybody said it was a great mouse. I got it, it was terrible. It didn't work on most surfaces. It didn't hold battery long.

Long story short, I will hold off until it stands the test of time for a bit.

Hope they bring the new tech over to the G502 (basically a wired version of the Performance MX suitable for work and gaming).

I no longer care about Logitech mouses after I had THREE premium mouses, in succession, to die to the same problem for me personally and additionally one mouse for a person that I recommended it to. All had exactly the same problem -- double clicks registered when clicking left mouse button.

For a premium brand I find it completely unacceptable. Even though it is possible to fix the problem (https://www.instructables.com/id/Repair-mouse-with-double-cl...), I gave up on Logitech mouses completely.

I hope they bring some of the newer improvements and more of the MX Master features to the MX Vertical.

I've found that I really appreciate the different ergonomics of a vertical mouse, but I do miss my side wheel and unlocking scroll

Logitech has top quality hardware, but their software is degrading rapidly.

Why does Logitech need to update the mouse software every so often? Installing fresh Windows 10 on a new computer, a popup automatically appears on the bottom-right to download and install Logitech software - without installing anything. This is built-in ads for Windows essentially. Also, Logitech wants us to connect to the internet to create a profile. It nags you constantly.

We need software engineers to push back on these things that are pushed on to them by marketing execs.

I have an M510 and I love it but it needs to be taken apart and cleaned every year or so. It accumulates an insane amount of crap inside it which if left unchecked will eventually lead you to think there's a software issue or wireless interference as your pages scroll up and down randomly by themselves.

Most people probably just replace mice once they start acting up because they either don't want to bother cleaning it or else don't realise it can be taken apart and cleaned easily which fixes 99% of mice issues.

Also worthy to note that Logitech has decent macOS support.

Does anybody know of any MX Master 3 modding forums or other resources?

The firmware and electronics in these things are fine, but these mice are one size fits none. In my case: way too small. I probably need one that's 2 times the size + preferably vertical.

I was thinking of doing a mod where I convert an MX Master 3 to a much larger MX vertical type thing. Shouldn't be too hard, but if I can think of this someone probably already did it. Right?

I am a long-time user of the MX series, having used the master 1 and 2 and multiple anywheres 1 and 2 for years, mainly for their free-scrolling wheels. I was surprised when Microsoft upstaged them with their precision mouse line, which has a "patented magnetic scrolling". It seems to me that Logitech is just playing catch-up with the "MagSpeed" wheels on the master 3.

For MX518 lovers, I've got a strong recommendation for G400s. The shape is almost the same and it's amazing how durable it is. The cable issue is still there, just like in MX518, and eventually (I am guessing) that's the reason I'll have to switch to something else.

I've been using both of them for years and years. Amazing.

The latest one makes my MacBook Pro emit an extremely annoying high pitched noise when moving. I think it’s due to the high refresh frequency of the mouse versus more traditional ones.

It sounds like a squeaky wheel or a squealing (real, animal) mouse.

Other mice do not cause this problem. I mask it out with noise canceling headphones but I’d love a nice mouse that doesn’t cause this behavior. I’ve tried ferrite loops but they do nothing.

I still have a pair of G5 mice that I use at home and work. It’s good to see Logitech bringing back that design! Other than the MX Master 2S I carry around for mobile use, I’ve never had a mouse fit my grubby paws do perfectly.

Other than a cable replacement and a switch cleaning, both of those original G5’s are still perfectly operational after over a decade of regular use.

I had 3 of these mice over the years and each one eventually the cable would go bad/loose, I think including my G5, and I'm no fast twitch fps gamer. Looks like they changed he cable on this new one.

Ironically I switched to the MX series (multiple mx2 and mx2s, home/work) and I absolutely love them apart from the problems I used to have where they'd stutter on every OSX machine I used them on. I haven't had that problem in maybe a year, though. Logitech or OSX BT update maybe.

I can't go back to a non MX scroll wheel. I love it.

Wake me up when they resurrect their most famous trackball: The Trackman Marble FX.

Mine was an MX510 and mine also broke down after a cable issue... and then the second one after that. I'm not particularly conspiratorial, but that's 3 out of 3 anectoble circumstances.

The new mx518 is not as good as the old one. It required some software that did not work properly on macs.

I still use my Mx518 and 310 for LoL and PuBG. They’re still superior in my eyes.

Do you know about the button in the thumb rest? That'll be #3 for me. It looks like in the Logitech literature this is called the 'gesture button', and if memory serves it was introduced on the original MX, when they took away the third thumb button.

https://scdn.slashgear.com/wp-content/uploads/2019/09/logite...

I think the original MX (what was it called, the 1000? Revolution?) had the three buttons and no thumbwheel and it was great for reading code and for playing a couple video games.

When they added the thumb wheel they moved the buttons too far back to be used comfortably. So it went in a drawer and I went back to the old one, found someone with leftover inventory and bought a spare for when the first wore out. When the second finally gave up the ghost I was not really playing those games anymore, but I still miss scanning code with page-up/page-down.

The 3 seems to compromise between the two. I just noticed it was available a couple days ago, so I'll be ordering one soon I expect.

Thumb buttons are hugely under-rated in my opinion. Its the sole reason I bought my G600.

If the wheel is 90% faster it seems like you don’t need page up/down shortcuts.

> Is the thumb-wheel on the MX 3 "clickable"?

It is not, unfortunately.

Their ambi mice are decent. I use a G300S at work, and I think they have some fancier mice that are also ambi while having features like wireless charging and the toggle for smooth/ratcheted scrolling.

The only company I know of that makes an actually left handed mouse is Razer. Decent hardware, but if you're on a Mac their drivers are even worse than Logitech's. There's nothing worse than having your mouse stop working because the internet is down.

Good point, for some it is like being forced to buy a two right shoes to fit upon your feet. Let alone the aspect of mouse size and the analogy gets down to shoes only available for right feet and then sizes 6 and 11 only.

With that in mind - how hard would it be to make a mouse which had a gel top that would mould to your hand. Could have a gel that is perhaps viscus when an electric current passed thru it and solid when not - allowing you to setup the mouse to fit your hand. As for buttons, well, that has been one of the easier ones to fix and about the only area you can customise a mouse (switch left and right mouse buttons) which is your standard OS configurable.

Though I'm not aware of any material that is viscous when a current is applied and solid when not - the other way around you have https://en.m.wikipedia.org/wiki/Magnetorheological_fluid

Razer made a left handed Deathadder in ~2011. They've since been discontinued, I have 3 of them and can't switch away. I've gone through probably 5 others. The tracking is nice and the feel is very good, but the scroll wheel is made from acrylic and tends to warp over time. The left, right, and middle buttons basically suck and wear down. The toothed shaft on the scroll wheel is also very tiny where it meets with the rotary encoder and is very prone to snapping off or wearing down due to friction.

All these problems and I fear I'll never see a better left-handed mouse.

Logitech G Pro Wireless https://www.logitechg.com/en-ca/products/gaming-mice/pro-wir...

I switch between my left and right hand every couple hours. The scroll wheel is great but no free scrolling. The buttons are amazing. I think I charge the mouse once every two weeks.

3D Connexion, the company that makes the 3D mouse (for CAD) also makes a regular mouse, and it is available left handed. I haven't seen one in person so not sure what the overall quality is like.
