Why all the trouble Logitech? Don't you read people's complaints online? Don't you already know you used bad quality switches, and now everyone is complaining?
This is not what I have come to expect from you!!
One reason I went for this mouse (even though I was aware of the poor-quality switch issues) was Logitech's great support in the past. I've been a Logitech customer since 2013. My first ever product was MK 710 and when the mouse in that bundle started double-clicking after 3 years, they honored the warranty and sent me a replacement very quickly. Now with this mouse, I've been going back and forth with Logitech support for 10 days.
They first started by giving me instructions on "updating the drivers, using the GHub app, trying a different computer" blah blah. When nothing solved the issue, they sent me a link to a bogus website, asking me to capture a video with my phone showing that their bogus website detects unintentional double clicks. Once I sent them the video, they responded "oh we couldn't open the video, could you upload somewhere else?" Well here it is! Enjoy the video I captured at your request!
All the trouble for what?? Just send me the damn replacement already. Given the whole work-from-home situation due to COVID, I would've expected them to support people who use various computer peripherals. Needless to say, this mouse is my daily driver at my full-time job, and it's really annoying that it's double clicking so horribly.
