Super easy to assemble though you're not a mechanical whiz. No tools required for assembly, just snap shelves into place. You can put it together in less than five minutes. With 4" full-swivel casters and an ergonomic handle - your new cart can move wherever you move! Use the locking wheels to ensure your tool cart stays safe and secure without moving. You don't have to worry about your water bottles or other items falling off because the edges are high enough to keep everything on the shelves. The open mesh style trays are nice for you as you may like the visibility of easily seeing what is on the shelf. Maybe you'd like the side-wall design to keep contents on the shelf itself. So easy to clean. Things cannot fall through the shelf mesh but It does not collect hard water spots as the plastic/wooden ones do. It helps to fully dry things if they aren't completely dry when put away
