Cannot click left button

I bought this gear for around 1 year but it seems broken. I cannot click right properly. I have to click multiple times to complete the task.

Many people, including myself, have the same issue. The button switches are low quality and work for a few months. Then start working intermittently. Logitech are aware of this issue and do nothing. There are no replacement switches offered here or instructions for replacement (requires soldering).

Personally, this is the last time I'm investing money in Logitech.

Same for me, poor form for an expensive product and only after 14 months

In this case, the only thing I can see is that click left button is broken.

If this item is still under warranty. It's best to make an insurance claim right away.
If you want to fix it yourself. Replace it with a new mouse switch. Require soldering skill (Make sure is the same item as your mouse)

The switch shown is wrong. The original part number is EVQ-P0D07K. This part is more clicky but may last longer: EVQ-P0E07K. Kailh Mute Button 6 * 6 * 7.3mm may work as well.
