    • Heavy and durable
Pattern Name: Safe

I finally settled on this safe for my valuables after some long research on Amazon and after returning another safe of different brand I had bought earlier. Oh, boy, this safe is really heavy and durable. It requires a lot of strength to carry. The walls and the cover are very thick. No sharp edges which is a plus for such a heavy item. Good space inside. Has a good lock and its easy to open with a key. However, after some use, the rubber washer inside the door fell off and I had to glue it back in place. Relatively low profile making it easier to hide. Unlike many other safes on Amazon, this one seems well-made with precision. ... show more

    • 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

    • Well built and it holds quite a lot
Pattern Name: Safe
Nice quality. Yes, the latch is tight. You know when you push the latch down, its nice and snug. Fits nicely in the back of my closet without taking up a lot of room. It's heavy. I couldn't lift it so I slid it down the hall. From looking at the photo you would think A4 folders would fit. They don't, but regular Manila folders do, so I'm OK with that. I feel better that all my original documents, certificates, jewelry, etc. are better protected. ... show more

    • Looks great so far, let's hope it isn't put to the test.
Pattern Name: Safe
It's bigger and heavier than I thought but it appears to work great. While I personally won't be testing the fireproof qualities, lets hope it stands up to a fire if I were misfortunate enough to have one. I can rest easy knowing it is waterproof though. (I HAVE delt with flooding) It fits all my 8.5x11 booklets perfectly and some 11.8 x 9.3 file folders. ... show more
