The assembly was ridiculous. I ordered 3 of these ceiling fans and each one was defective. The holes were not placed correctly. When trying to place  the shorter light attachments, the longer attachments covered each hole. Good thing my bother was handy he used a drill bit to cut grooves into the longer attachments to allow placement of the smaller attachments. Unfortunately I bought these sometime ago and passed the return window. He made it work and it looks nice installed but it was the worst assembly ever.
