The Ready-to-Assemble Extra Large GearBox is a really sturdy storage unit.  I am able to store a lot in it and store somewhat heavy stuff.  The Ready-to-Assemble Extra Large GearBox seems sturdy and well built.  I have s lot of tools and other things that I have putting inside it and I will continue to add stuff until full.  I really recommend this unit. [This review was collected as part of a promotion.]
