Tough enough!
For the price is does what I want exactly, it holds enough of my cordless tools(trim circ saw, jigsaw, multitool etc) and other things like quick clamps chargers. Reasonably stout, i have the box loaded with 25lbs, i have a drill case latched on top with lots of batteries, and then an 18" soft bag full of hand tools resting on top of that. The handle does not flex much at all while loaded and it feels stout. It actually tilts back to allow the lid to open completely. I would not drop this down the stairs or let it slide around in the back of a truck, but if you take care of it, it'll keep your tools dry and safe. If you are working in a building where this will need to descend stairs while loaded, I would splurge for the full metal rack system.
