Bloody that I bought three to four years ago and the bloody that I bought recently are very different. The same tried-and-true model that has been in service for a considerable amount of time, demonstrating its superiority and dependability. But unfortunately, the new mouse is not even close to being as good as the older models. Low-quality plastic, in general, a cheap design, echoing, as if the room were empty, light, LMB clicks on the entire apartment; highly repugnant. It is unpleasant to touch as well. Extremely disheartened.
