I am very happy with this purchase. It is very spacious, the Suspension files A4 20pk (sold separately) with plenty of paperwork and folders in them fit in just fine. I can also store a couple of 15" laptops in there too with space under the suspension files for USB flash drives, SD cards and the like. It is (reassuringly) very heavy - if you leave it on a carpet, it will leave indentation marks - best to find either a hard floor or store it in a broom cupboard or somewhere where marking a carpet is not so important. To open and close the lid you must put a fair amount of pressure on the top due to the watertight seal - not a problem for me but I think opening it would maybe be an issue for some. For under £100 this is an absolute bargain and I would definitely recommend this for safeguarding your important documents and media.
