Shame on them!!! I've bought and used in the last years up to three different anywhere mx —the 2, and a couple of 2s—, and all of them got after a couple or three years of use the phantom doble click problem due to their sh***y Osrom switches. Everybody knows it. Internet is full of pages dedicated to try to solve it. And know Logitech come up with this. Shame on them!! I would never again buy them a mouse. As a matter of fact, after my last disappointment I've got myself a Chinese copy for less than half, which, by the way, works even better: quieter, and with longer battery run times.
