    • Great quality and use
Pattern Name: Safe
This is really great to keep all my important documents in and it’s not too big so it doesn’t take up much space.

    • Fantastic customer support
Pattern Name: Safe
The customer service at SentrySafe/Masterlock is incredible. I had a small issue with my safe, and they made the situation right. I absolutely recommend this product, or another from the Masterlock/SentrySafe product line, because of their response to my issue alone. The safe is alright. It's nothing to write home about, and that is to be expected at under $100. It is the exact width of a "normal" manila folder, and it would be nice if it was just *slightly* wider. I would like if the lid had some sort of resistance to prevent it from being slammed. I don't have any major issues with it and I don't feel as if I'm going to break anything unless there is a manufacturing defect or I mishandle it. The handle does flex a little if you try to open the safe while it is locked, but it fine with normal use. The key isn't reinforced and will bend if you push on it the wrong way. The gasket might fall off and need to be put back into position before shutting the lid again. Those issues don't worry me now that I've dealt with their customer service department. I contacted them for one of the issues I listed above and they fixed the problem quickly and completely. Fantastic customer support. Fantastic customer support. ... show more

    • After several months, the seal on top came off. Very heavy.

After several months, I open to put something in and the rubber seal came off. Looking for a way to put it back. Does not seem to be glued. Heavy !

    • Hanging Files not included :')
Pattern Name: Safe
Build quality on this is very nice. Very sturdy and feels like it can take a beating. Perfect for storing sensitive files, and is quite spacious. Knocking a star off since all of their advertising/promotional pictures for this product include the hanging file dividers, however those are not included, and only mentioned in a tiny section of the product description. Would be nice for them to include, or also provide imaging of the safe without them ... show more

    • Would recommend to anyone looking for a small safe for documents!
Pattern Name: Safe
Works exactly as intended! Lock seems secure although it is a little tricky to lock sometimes. Safe is very heavy which I believe is a good thing. Great value for the price!

    • A Safe That Actually Feels Safe
Pattern Name: Safe
SentrySafe’s black fireproof and waterproof safe earns a full five stars because it does exactly what a safe should do. It sits there quietly, looks unbothered, and gives you the reassuring sense that even if the world outside is doing its best impression of a disaster movie, your important items are staying protected. The build feels solid and dependable, with the kind of weight that says your documents are not going anywhere. The fireproof and waterproof protection is genuinely confidence-boosting and not just marketing fluff. It is the kind of feature that lets you relax knowing a burst pipe or a kitchen mishap will not turn your valuables into a soggy mess. The interior space is well designed for passports, documents, small electronics, and all the random items you suddenly realize you should secure. The lock mechanism feels smooth and sturdy rather than flimsy or temperamental. It is one of those rare products that inspires real trust instead of wishful thinking. If you want a safe that feels genuinely tough and ready for whatever chaos life throws at it, this one delivers without any drama. ... show more
