Screw holes not lined up on mounting bracket. This caused entire fan to not be level. Had to drill new holes and use shims. Screws stripped out easily... made in China... beware.  Instructions should state that bracket must be flush and level to ceiling before proceeding. Took an experienced handyman, who has installed many ceiling fans, approximately 6 hours.
That said, it’s an attractive fan and puts out nice air flow. Has remote to adjust light and fan speed and direction.
