Review: Heavy Duty and just heavy - This thing is heavy duty, and just plain heavy. I know if it experienced a fire, everything inside would survive. Unfortunately, because it is so protective, it doesn't hold much. As others have said, the key lock is a little finicky, but I haven't had an issue with it. (Again, it doesn't hold much, so I put in my important documents that I don't need access to a lot) I also registered it on their website so if it were to be in a fire, then I can get a free replacement.
Review: Good Home Safe - For the price this is a well built and heavy home safe. The locking mechanism is fairly lightweight but then you are not trying to stop Oceans Eleven. Will keep my important documents fire safe and dry.

### ⭐⭐⭐⭐⭐ Heavy Duty and just heavy
*by B***C on June 30, 2025*

This thing is heavy duty, and just plain heavy. I know if it experienced a fire, everything inside would survive. Unfortunately, because it is so protective, it doesn't hold much. As others have said, the key lock is a little finicky, but I haven't had an issue with it.

### ⭐⭐⭐⭐⭐ Good Home Safe
*by A***R on April 18, 2026*

For the price this is a well built and heavy home safe. The locking mechanism is fairly lightweight but then you are not trying to stop Oceans Eleven. Will keep my important documents fire safe and dry.

### ⭐⭐⭐⭐⭐ Its Strong And Well Made!
*by A***R on June 21, 2025*

I'm glad I bought this safe. It is strong and fire proof, heavy too! I had to figure out the locking system though. I have to turn the key and then press down on the top, hear a click, then I can open it. I don't know if this is the design of it, but it it works. It locks, it opens. The inside of it is a nice size, and the file folders are great. They allow me to organize my safe, to put my papers in order. I think the price wasn't bad at all for it, and would gladly buy another if it was needed.
