While other outdoor storage boxes can cost over $100.00 , this storage box is the answer to the budget minded person. Easy to put together , snaps into each other. Just don't jump the gun and start putting it together only to take it apart and rebuild it , this time looking at the instructions,like I did. Empty , it's easy to move around . No wheels on the bottom. If the lid doesn't quite line up with a corner of the storage box when closed , one of the bottom corners needs a shim to line it up. This is only if the floor is uneven.
