### ⭐⭐⭐⭐⭐ Heavy and durable
*by R***Y on 15 February 2026*

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.
