I bought this device in June 2022. A year later, we can sum up some results: the mouse is worth its money, the dual sensor allows you to work on many different surfaces, it fits perfectly in your hand - zero discomfort, the keys did not play, through experiments with weights I found their ideal combination for myself, the presence of a detachable cable allows you to replace it yourself in case of a break. More about the cons: the front side key does not work everywhere, so you have to assign its functions through macros; the soft touch is really normal to get dirty like that, but if you keep it clean, the mouse will look like it was on the second day after purchase; upset the rubber bands on the side panels - after three months of use, the glue just dripped, and I had to return the rubber to its place using the method, which is just a huge minus for such a mouse.
