Not sure why everyone is so frustrated with the assembly  Sure the directions suck and parts may not be labeled the best. I contacted them and they sent me a video on how to assemble it. Done in 30 min or less. Please use technology first before you start giving single stars. 
For anyone who still needs it, hop on YouTube and search ‘how to assemble the ceiling light’  or…here’s the link. httpsyoutu.beZQdQcqphDto  enjoy. 
Light is awesome and as advertised.
