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).
This cabinet is good for the person who is not real concerned with security. The lock only secures the left side of the cabinet. I returned this cabinet as it was not as industrial as I was hoping. A little too flimsy for my needs but a nice produce for storage.
