I have bought plastic shelving units in the past and this is my first experience with a heavy duty metal unit. You can definitely tell and feel that this is of a superior quality that can handle the heaviest of items on each shelf. However due to its weight it makes it hard to move around and feels bulky. Overall I think this is a great buy and awesome spot to store your garage and shed items in one central location. [This review was collected as part of a promotion.]
