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.

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.

Logitech software is a dumpster fire. For a while there it would start and go to 170-190% CPU and just burn until it was killed. I share your experience and frustration.

I'm so glad linux usually contains reverse engineered drivers that are open source so everything just works out of the box with logitech.

I recently made the switch to Linux and I wouldn't quite agree with this. The bare minimum works, and I'm very grateful to the people volunteering to achieve that much, however my productivity has taken a big hit with no official Linux support from Logitech or Razer.

I had become very dependent on my mouse automatically changing profile depending on the process that has focus in Windows. In Linux, there is zero official or community support for that. I've had to shoehorn several profiles into one and use manual switching which is awful - first world problem, I know.

I'd warn people to expect a bad time on Linux with their peripherals, and I'd urge these vendors to pull their finger out and support Linux.

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…

Wow the G604 is a really good looking mouse as far as PC mice go.

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 loop…

I have the same problem! What the hell is that? I've been mystified at that noise for ages.

Looks like a number of Logitech mice suffer from whine, though whether it's the same whine as parent is describing I do not know. Apparently caused by a poor choice of capacitor: https://jdc.koitsu.org/logitech/ (you'll have to scroll down a bit).

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.instructable…

IMO it's an inevitable result of using mechanical switches. I love Logitech mice but I'll usually get n-1 versions that go for cheaper, so replacing every 1-2 years doesn't sting as much.

FWIW Razer has a new mouse that uses optical switches (Razer Viper). It'll be interesting to see if how their switches hold up a year or two from now. I've heard similar complaints about mouse switch failures with Razer mice as well, so it's great to see them attempt to address the problem.

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. [1] https://www.techpowerup.com/review/logitech-g-mx518/

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

It's placed over the antenna for the Bluetooth LE chip. I'm assuming it's related to antenna tuning/calibration.

That the ruler is related to the antenna tuning is the initial guess of the author too, but he is unsure. But come to think of it, why is the PCB silk-screened in the first place? I don't think such a cheap board will ever get serviced by the manufacturer, and slikscreening is cheap but not free. My guess is that it is "just in case". If something goes wrong, the silkscreen is there so that things can be fixed by an…

Virtually every board is going to need some kind of marking, so if you're doing a silk screen anyways it almost free to add more stuff to that silk screen.

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.

I'm really curious about the silkscreened ruler. Can anyone solve the mystery? https://blog.bolt.io/wp-content/uploads/2019/10/DSC02786-102... https://blog.bolt.io/wp-content/uploads/2019/10/DSC02791.jpg

I'll go with occam's razor and say it was simply not removed from the development board to the full production board.

It's probably related to tuning but on a production board? Normally if you need it as part of your production process it would just be part of the tuning tool itself.

But honestly I cannot see how it would be used in production since the antenna length is determined by that point.
