Umbrella appears to be of good quality, but the tilting mechanism does not work the way I would have imagined.  Instructions states that one turns the crank to raise the umbrella and then continues cranking to tilt the umbrella.   Cranking gets very difficult.   Instructions warn not to over crank, but umbrella does not tilt very much when the cranking becomes very difficult.   I cannot figure out any way to tilt the umbrella other than cranking, which does not work in a satisfactory way.
