I got mine for files to travel with back and forth but it doubles as a carrier for misc. items. You know why you need it. Its worth it when you get it.
This is just what I needed for those files too large for a regular filing cabinet. I do not need a legal sized cabinet but do have some files that too long for a regular. This suits them perfectly.
The structure and support ribs give this box good capacity (about 1/2 a lateral file drawer per box) it remains to be seen how durable the material is since I have only just purchased them. The handles that latch the bin and lid are very easily knocked loose which is a nuisance during active loading/unloading and does not bode well for storage. Stacking is not quite as secure as other brands.
