This unit shipped faster than I expected. It is not heavy duty, but then again it is a pretty great value given the pricepoint. You can get a heavy duty quality version of this type of shelving unit for 5x or 6x the cost. I don't plan on using it as a ladder or storing massively heavy machinery on it. It is plenty durable for my needs and importantly, it is stainless steel with very easy to clean surfaces that won't tarnish or oxidize in response to cleaning agents or other solvents. I bought a second unit after setting up and inspecting the first one. Like some Ikea products the name of the game is to be as cheap as possible without being too cheap. All of the edges underneath/behind the curled lip of the shelves are tucked in so you won't accidentally cut yourself when feeling or grasping from underneath the shelf. This is a detail often unattended to in cheap products. Assembly took me maybe 30 - 40 mins. My only negative critique is that both units arrived with some dents and dings in the outermost shelves as packed. The boxes were pretty beat, it was obvious that the shipping agents did not handle with care. Nothing I found too bothersome, but they could stand to add a foam or bubble wrap layer between the packed unit and the cardboard box to hedge against abusive delivery.
