Review on Logitech M590 Multi-Device Silent Mouse by Kenta Kajikawa ᠌

I looked at the reviews, no one wrote about the problem with the left key. I don’t know - either I’m so lucky, or other mice with a similar defect were not included in the statistics. Has some pros The mouse is good overall. Comfortable, works well on most surfaces. It can work with two devices at once, there is a switch button (we have a computer / laptop pair). Normal working mouse. Cons: This is my second mouse of this model. The first red one, we have been using it for about three years. And at some point, the left key began to work poorly for her. It didn't always work, I had to press harder. The mouse fell a couple of times before it started. Decided that was the issue. And then the key stopped responding to pressing at all. I opened the mouse, checked the contacts, everything is ok. And I found that the matter is in the button on which the key is pressed. When pressed normally, it does not work (pressing the plane from the key), but if you apply a point force (for example, with a thin screwdriver to the center of the button), everything is ok. I solved the problem by installing a mini gasket between the key and the button. And so we bought another such mouse, gray. Three months have passed. And . suddenly, at one moment, the left key stopped working!
