One of the major problems with rolling toolboxes is that they are constructed of steel. Inevitably over time they get dinged, dented, and then start to rust, particularly if utilized in a damp environment. This product, on the other hand, is an extremely sturdy plastic; if it ends up sitting in a couple of inches of water when the garage or basement gets some water, it won't suffer as a result. There's no "give" to the plastic - I tried using the top surface as a ladder, standing on it (probably not recommended by the manufacturer) and there was no give at all. The drawers pull out smoothly and easily, even when weighted down. There are some intelligent design features here, such as the little indentation that will catch a rolling pencil before it rolls off the top, or the easily swiveling rubber-coated wheels. There is a minimum of construction necessary when the product arrives....attach the four wheels (a driver drill is a big help here), the handle, and the handy AC strip and you're ready to go. If you decide that the unit is going to be in a fixed position and will never be moved, you can leave off the handle and the wheels; the unit has an underside design that allows it to sit flat and firmly in position without the wheels.
