Logitech MX Master 3s Left Button Malfunction Fix 

For a mouse at this price point, it shouldn’t have an issue as consistent as this.

Interesting I have the same issue. Good job fixing it. I won’t be going through this stress, but will make sure to avoid Logitech mouses in future until they fix this.

After a year stop working the left click but with this now its working , thanks!!

Thanks for the video. I hate that the features are good, but the clickers are almost always garbage. Maybe it's to hard to build good clickers, but I really doubt it. Mine is 18 months old and both sides started doing this.. feels like planned obsolescence. Now I have to use the Amazon customer service, solely to let Logitech know that this does not work. In my country we usually have 24 months warranty by law

My Mx Master 3S has the same issue and your video is helping me to fix. Thank you a lot!

my mx master 3s right button died just after the warranty expired. fuck logitech.

I think that with Logitech MX Master 3S you can use Kailh Mute Button 6*6*7.3 Silent Switch

Hi man, faced the same issue after 13 months. Ordered the new one microswitches and waiting for them

I have had all the mice in the mc master series. And the mc master 3 is the first one I had an issue with which is such a shame. Unfortunately for me I am a year out of warranty so Logitech will not repair it I was offered a 20% discount on new products... Why would I want to buy a faulty product

where did you buy that piece?

I also have the same issue post 18 months.

SAME PROBLEM AFTER 1 YEAR

Thanks

This doesn't seem attainable. So it's this or a new one?? 😩

Wish i had your skill to make this repair. Instead, im out $130 after 18 months. They "generously" offerred me 30% off a new piece of crap, rhough. 🙄

Where did you got the switch is it original or not

I hate Logitech after using their multiple devices for last 5/6 years. Currently using mx master 3s and keyboard G213. Left button of the mouse isn't working (click, drag, select problem 90% times) after exactly 1 year. So I'll not get any warranty here. Also keyboard button "x" doesn't work in my G213. I had to use on screen keyboard 4 times to write "x" for this comment. So, you can understand how much I hate this brand Logitech. And in future I'll always avoid this garbage brand. I'll try anything but them.
