Review: Water Resistance - All quality
Review: UK buyers take note - UK buyers note this box is designed for USA A4 hanging files so UK A4 hanging files won't fit. It does take A4 wide paper - see pic (contrary to other reviews) but only takes "letter size" hanging files. In the UK I only found 3 or so outlets on desertcart that sell this size, since most UK outlets sell "A4" size which at 31.5cm wide is 1cm too wide. Otherwise a sturdy box that looks like it will suit our needs. It is quite heavy and with no handle is a bit cumbersome to move around. Unlike other reviewers I'm not bothered about the simplicity of the lock (we didn't get it for security, just for its fire proof capability) or the plastic clasp. The clasp is likely to melt in a fire but that's fine so long as the contents are protected. The supplier also states in the instructions that the box will need prizing apart after a fire but, so long as you register for the warranty, they will replace it for free. So no worries there. The lack of a handle is a bit annoying and the lack of a model that takes 31.5cm wide hanging files is perplexing for a product sold in the EU. Otherwise very happy so far. It also arrived 3 days early so well done SentrySafe!

### ⭐⭐⭐⭐ Decent heavy safe
*by A***R on 16 February 2024*

Seems like a good quality, heavy safe. It arrived in a box which was un-damaged (which was great considering the weight and the distance it had travelled). The safe was pretty dusty/dirty I needed to wipe it down. It could do with being inside a bag first. Only problem is the inside is small! The A4 hanging files can be bought in the slightly narrower option so they fit inside but the metal hooks still make them too wide. As you can see in my pics the hanging files have to go in at an angle. As for A4 paper, if it's in an envelope it won't fit but take the paper out the envelope and it fits quite snug. I guess the Americans must sell different size hanging files.
