Review changed. The previous mouse was replaced under warranty by an official service center. In addition to the LOD problems and cursor jumps that were reported in US Support and were recognized as a defect, there was also a problem with disabling the mouse at an equal place in wireless mode. The 2022 support for Razer has replaced the sysh. The problem with LOD and weight, which I spoke about earlier, is still relevant. But with some calibration of the carpet, you can come to a more or less acceptable behavior for me. Having got used to it, after a couple of months I am satisfied with the device. For players with a "swappable" mouse control technique, this device is still, in my opinion, a dubious choice. But other than that it's a great mouse.
