The third M90 with the same error

I thought when I first Logitech M90 that a strange error with the left mouse button only affects my copy. After several months, the mouse makes an unwanted double clicking the left mouse button, because the key has given way over time and the game between click-solver and forefinger storage was insufficient to allow reliable click-control.

The second M90 has developed a similar mistake about the time. The scroll-click (very useful in Firefox to click a tab and close) was gradually sluggish until he was ultimately unpredictable.

My third M90 which I ordered through Amazon now has the same mistake as my first M90 that I had purchased from a department store.

I find it a pity that the mouse has not evolved or was reliable in order to use it without substantial material wear for more than about one year can.

To be fair, three stars because it is very light and otherwise accurately navigated.
