Before this mouse, I went through several models of different price categories. Everything was not right! For a 4K monitor, I set high DPI values and the behavior of mice became inadequate: either brakes, or incomprehensible accelerations, or problems with precise positioning, or the inability to double-click, because. the mouse believed that I first made a click, then moved it, then made a second click. Thus, often when trying to open a folder, I moved the selected folder to another. The same mouse behaves absolutely correctly in all situations. The mouse is quite light. But for me it turned out to be a plus. Very easy glide and precise positioning. In general, the sensor works out with a bang. How reliable the mouse is - time will tell. So far, I am very pleased that I finally found the most comfortable mouse for work.
