This is an excellent brand anything by Gladiator has always been the workhorse - always steady, strong and performs well.  I ordered two separate units - a cheaper unit I will only use for Christmas decorations - and these Gladiator shelves for everything else.  Goes together very easily - has the dearth to handle wide objects. I have boxes from office heavy with professional books  files and the shelves don’t sag. I highly recommend this.
