At first I was pleased with what appeared to be very solid metal. unfortunately , the front peg leg that is supposed to balance the front of the shelf is way too short. i am improv by using a much longer screw and dropped bigger nuts over the screw , and then screwed it into the peg leg. it worked , and you cannot see the nuts behind the shelf. also, tightening this screws and bolts.\nWhile putting it together folds in the bars quite a bit. Less is more perhaps. It serves its purpose for what I needed a shelf for.... Cannot beat the price.
