It's like a demon has possessed it! I leave it alone and the cursor moves on its own whenever it wants on the screen, as if something evil has entered it! It also has its own personality: it makes its own choices, I want to click OK and it goes out of the selection and goes somewhere else on its own! If you want a mouse with character, it is the best choice, I highly recommend it.

I bought the 175 in the morning, which doesn't work on either a wooden table or a white A4 page. I exchanged it and got the 165, which works perfectly!
