Overall very happy with the desk. The instructions are very straight forward but if you aren't paying attention you could attach something backwards or upside down. It took me about 20 minutes to set the desk up.  In step three if you don't have a spare pair of hands, flip the table right side up and attach the trays on, it makes it easier to not be fighting gravity. When attaching the support arms on the back, the 80 degree bend end attaches to the center of the desk and the 35 degree end to the leg.
