After 2 weeks of use, the mouse keys became quite rigid, you already need to press hard on them to make a click, or “loosen” the key to the desired position so that the clicks pass normally, but still some discomfort arises. For 3000, the quality is simply disgusting - even on the simplest Chinese mice, clicks are made easily and naturally. For me, this is the last mouse of this company, Logitech has completely forgotten how to make peripherals. An office mouse like the mx185 died within a year of getting double click disease. Only the very first game room lasted 3-4 years, but at the end it was replaced due to the same disease of double clicks.
