For mobile mechanics, this box design will prove perfect. It features a long pull-out handle and sturdy rubber wheels, which makes it easy to move from place to place. We were also impressed with the removable trays in the lid and the tote tray inside. However, the case isn’t lockable and tools have to sit on top of each other. While we managed to fit all of oursin, you have to root around to retrieve each one, which could be awkward.
