These cabinets are super sturdy and generally high quality for the price point. The only issue we've had is that for some reason the screws that attach the wheels are extremely difficult to screw in. I think it's because the holes in the sheet metal are just barely too small so the screws have to shave down the material a little as they go in. You'd think this unit would be quick to assemble given that you only have to attach the wheels and drawer handles but these particular cabinets have given me trouble every time. I've even tried with a power drill but the resistance was too much for it to turn the screw! They'll go in eventually with enough elbow grease (and a good screwdriver) but it's definitely a pain. Still worth the value for this price though ($140 business pricing at time of review).
First one damaged in shipping returned replaced in one day. Cheaply made; screw-on wheels have no locks so cabinet scoots around as you access the drawers. Bought same size/manufacturer wheels on amazon WITH locks...solved scooting problem.
Would not recommend this product. It had a dent the size of a baseball on the side that I didn't notice until I had it assembled and partially filled it. It wasn't worth trying to exchange given my commute distance assembly packaging. I wonder if they dent very easily the floor model was dented as well.
