Either Logi forgot how to make mice, or one of the two. I bought a wretched m190 instead, which, by the way, cost 700. Broke after a couple of months, started doubling one click and rang wildly. I searched with a quiet click, I found it with the word Silent, I thought it was Logi - it means quality. The mouse is made of the most plastic, there is something to compare with. I have 2 different HP mice, one is silent, the other is gaming. So there the plastic is soft, pleasant, pressing is clear without ringing Carl. You press this a little harder, the spring rings, resonates. I'm a little confused how you can write the word Silent, well, a little quieter than a regular mouse, but why does it change the sound. Roller miserable, also sonorous. Cosmic price tag for this.
