It’s a pity that the manufacturer cheated so much and misled the consumer (I saw a footnote about the comparison with the Logitech M170 model, but this, of course, is a trick), after all, it’s 2022 and it’s not about a cryogenic engine, you could try to work with the wheel for such a cost. Got pros: No, because what the manufacturer claims cannot be called a virtue. Therefore, I simply state a fact - the sound when pressed is really quiet, but this is not a virtue, but a property declared by the manufacturer, as it should be. I did not find other positive differences from the M185. Has some cons: I'll just quote the manufacturer's website: "Silent Scrolling.". This, you see, is a lie. Scrolling is significantly louder than standard non-silent models.
