I own 3 logitech G600 mice now because the button switches wear out. I think I'd be more impressed if logitech put hot-swap sockets in their mice for the switches (asus is doing this on their mice).
I learned that those switches are actually pretty standardized and you can just desolder them and buy proper ones for ~1$ and at least my older G500 could be opened and disassembled fairly easily.
My G600 started double clicking ~2yr ago. I hate replacing things, so I tried a bunch of guides to fix it - opened it, cleaned the switches, soaked them in alcohol, etc. It would stop double clicking for an hour but then would happen again.
Was going to pick up a new one when I read a reddit comment that said it could be static buildup in the mouse & that just spamming both the buttons at the same time for 30s could fix it. I did this and ... it fixed it. I also usually hold the mouse upside down while doing this so maybe it was just dislodging dirt that the alcohol didn't get. Who knows.
In any case, holding the G600 upside down and just spamming r+lclick for 30s generally solves the problem for me for at least a few months. (I've been heavily using the mouse since ~2016) Maybe this helps, maybe not.
Side note - I love this mouse. Tried to switch to a Razer mouse and it broke within 3 months. RMA'd it and the replacement had a bad side button so I just gave up and went back to the G600. It's not ideal for my use case but finding a good mouse does seem impossible these days.
Ok, I don't know what is this dark magic and how it works, but it mostly helps, reducing double click on my old G602 by A LOT.
Thank you very much dear stranger, you were the best part of my day today, saving me a hundred bucks :) .
PS: on my desktop I've been using Asus Gladiator wired mouse. I can recommend it, no sign of doubleclicking over a few years. Just don't buy revision with rubber inserts, those came off eventually (but can be glued back).
I've got two Logitech G500s mice, and the buttons broke on them too.
What I did was sourced some replacement Omron switches that have a "made in Japan" stamp on them, vs the ones that were in the mouse labeled "made in China".
It seems that the switches made in Japan are higher quality/have better QA.
Same. Lost a perfectly good G403 Hero to double clicking and spinning out. A quick perusal through r/MouseReview shows that this is nearly an epidemic among Logitech users
PSA: optical switches cannot ever get the double click issue. There are quality inexpensive optical switch mice to choose from as well.
