Pros below: I always take this particular mouse for its noiselessness. The sharp clicks of ordinary mice annoy me. This mouse has the lowest price compared to the prices of silent mice from this and other manufacturers. With its cons: The disadvantages include a limited service life. In my case, after about a year, the left key starts to fail. The mouse will probably last longer for other users. The fact is that I play a lot of video games where the left key is used to the maximum. That's why it wears out faster. But I'm quite satisfied with changing the mouse to a new one once a year. Because that's what I'm used to. I like her the most.
