Assembly was slightly challenging, but we were able to get it set up correctly using the instruction booklet.  After using it for four years, the hinges rusted to the point that they needed serious attention to allow the doors to open.  Was able to get them working again, but they seized up entirely the next year.  Excellent customer service (by phone) was helpful in confirming my order for replacement parts and indicated that I would receive them without charge!  I would suggest that Lifetime include instructions on maintaining the metal parts to prevent these issues (or lengthen the service life of the parts).
