With the Linux kernel, USB power savings are also annoying on Logitech devices. If you set everything on USB bus to powersave, their mice and keyboards will go to sleep every few seconds unless there's continuous activity.

I have experience with Dell and Apple keyboards on Linux, and they don't suffer from this issue. The problem is not terrible, but requires a special udev rule to exclude them from powersaving, which is annoying.

Also they've been very slow to adopt optical switches compared to other brands, a handful of their high end gaming mice have them, but the vast majority of their range still uses the same old mechanical switches that tend to start erroneously double clicking after a while.

If your mouse starts double clicking, play a game of Quake 3 for an hour, or just click a bit more aggressively for the next hour. It clears the problem, per my experience.

What I understood is, the switches on these mice (I have G700) are practically abuse-proof. However, they don’t like to be used lightly and start to glitch possibly from fine dust. Using the switches more aggressively cleans them up.

My first generation G700 still works great.

That sounds like a job for contact cleaner, assuming it’s possible to non-destructively get a tube next to the switches.

I’m about to open my second bottle. My first bottle is from the 1990’s.

No, it's a job for a sewing needle or a toothpick. Logitech switches can be temporarily fixed by disassembling the switch and adjusting the contact plate inside because it gets bent out of shape and stops registering the clicks correctly. But it's easier (and more reliable) to replace them with higher quality alternatives while you're in there.

The G700 in question registers clicks correctly for 14 years at this point. The problem in my case is very light clicks and dust ingress to said switches. I have 10+ year old M705 mice which doesn't have any switch problems.

Their switches are just crap. They use Omron switches mostly due to their low cost, even on supposedly "high-end" mice. People routinely replace them with better alternatives (e.g. TTC Gold or Kailh, but there are lots of them) and get years of heavy usage after that without any problems. The switches can be obtained on aliexpress, you do need a soldering iron though.

I mean, if a mouse is working for 10+ years for 8 hours a day (M705) or for 14 years for 2-3 hours a day (G700) without any major problems, I wouldn't call that switches crap.

But that's only me, of course.

It’s not just a soldering iron needed. I replaced the switches on my 17-year-old Logitech MX Revolution and on a newer Performance MX and the old switches are completely impossible to remove from the PCB without snipping away at them and a lot of (careful) force. However I can say that the result was worth it, no more phantom double-clicks. Mouse itself was fine.

Maybe for some of the newer mice it’s an easier ordeal, though.

The issue is actually the static electricity buildup in the plastic somewhere. It doesn’t happen if the air is humid enough.

So, just turn off the mouse and blow in it a few times. It will work normally for a few days after that.

I found this solution on approximately the 12th page of a Google search ~9 years ago. Every other solution was wrong.

The left-click switch on my Logitech G305 started glitching-out after a couple years, particularly noticeable when trying to drag something, the drag would drop randomly in the middle. Disappointing to only last a couple years.

I found replacement switches for $10 on amazon, pre-wired with little plug, easy enough to install with just a micro-screwdriver, no soldering. This problem is common enough that there is a good selection of different switch brands/types available. Fantastic. Not disappointed at all anymore, honestly.

I also have a G305 where the left click button wore out.

I removed a switch from the Pi 400 desktop kit mouse I had laying around and replaced it with that.

Upgraded the slider pads while I had everything apart. These actually made more of a difference than I anticipated.

Virtually brand new, although amuses me that left and right click sound different now.
