In general, the software is a complete failure. It makes it impossible to use the mouse. Constantly after ating the G Hub, it gets into an endless download and then downloads something, then loads the disk at 30-40 Mb / s, but does not delay it. You need to remove it and reinstall it. But even this does not always save - it still hangs when loading. You have to look in the registry and system files for the remnants of garbage from the software (cleaners and super software removers do not help in this case). When ating, the settings fly off - you need to re-set everything. First, the left button began to fail with a double click. After contacting support somehow managed to solve. Then the same problem with the wheel - double click or double swipe. Reflashed - gone. Now a new problem - scrolling with the mouse changes the DPI. Already tried everything - the problem does not go away. Support didn't help either. So far fixed by deleting all DPI values in G Hub except for the one you need. In general, you don’t use it, but you dance with a tambourine at least once a month. I want to throw it out the window and buy another one. And forget about Logitech as a bad dream. : the scroll fell off - it stopped scrolling with the middle button (rotates freely). They changed it under warranty . and exactly 2 years later the scroll fell off again. Dump this brand
