I might be confused, but the tilt mechanism seems to cause thing to blow over in a breeze and seems like someone could really get hurt by it. If you don’t stop the crank over the told mechanism it just blows over and falls on its own. If I had been sitting at the other end of my table it would’ve hit me in the back of the head. There does not appear anyway to lock it from doing that. Seem to be a bad design, and no paperwork in the box colliding to this function. Maybe mine is broken, feel like for a the money it could be a little better.
