When the mouse is connected to the computer via a 2.4 Hz adapter, the mouse cursor on the monitor starts to creep very slowly, uncontrollably, there is no reaction to pressing the buttons, the only thing that did at least something was the wheel, when scrolling, after 30 seconds, the window moved, but such good luck too it was necessary to catch, when connected via bluetooth, nothing happened at all, except for a very slow, uncontrolled movement of the cursor in one direction.
