Fan is beautiful. We had to use the 21 inch rod, but we couldn’t balance to keep it from shaking. We did notice pictures of customers that used the 4 inch and were extremely pleased with the fans. We even tried using the balancers, but didn’t work. Still gave it a five star for all the  plus reasons above, but also how extremely Wayfair handled our situation and takes care of you with 
personal customer service.
