All in all a very good little tool box. The included parts holder is one of the best I've seen and does a very good job of organizing small parts. The included tool tray is good and can be very handy. The metal on the main latches is sharp and needs to be ground down. Typical for this type of metalworking with stamped parts. I will be using the parts cabinet partially separate from the tool chest as the parts cabinet takes up a lot of space in the tool chest. This is a very nice addition if you're sanding down the rough edges on the metal and if you're careful with the compartments on top because the locking mechanism is questionable. I probably just won't use them.
