I didn't expect such a serious item at this price. The steel is thick and heavy, and the joints are cleanly welded. This looks like it will last a long time. The system for mounting things inside without piercing the outer case is well thought out, and it comes with a grounding wire for the door already installed. My only small gripe is that the lugs used to attach it to a wall seem to be uncoated. I guess I'll have to paint them.
