>>10860198This supposedly "intuitive" grinder/polisher took some time to get the hang of: for the life of me I could never remember the combination of short and long presses on the power button to get the right rotation speed and direction.
But then I remembered that it is supposed to have gyroscopes(?!) in it. Well, what do you know? If you flick your wrist clockwise while holding the power button, the thing starts rotating clockwise and vise versa. And the more vigorously you flick it (or the more irritated you are), the faster it rotates. First time using a tool like that.
