Review: Quality product, but hard to handle - Good solid safe, but needs a handle due to the size and weight.
Review: Good Safe to Keep Important Documents - We needed a spare home safe and after shopping around, we bought this one. Probably too heavy for a handle so we can't complain. We placed some furniture sliders under the box to make it easier to slide on the floor. We hope we found an ideal hiding spot. Would be nice if the inside measured just over the side of a sheet of paper. The safe itself seems to be of high quality. We have a mid-size Sentry but needed to store additional documents. This new one was easy to set up and are having no problems with the locking mechanism.

### ⭐⭐⭐⭐⭐ Quality product, but hard to handle
*by S***. on July 24, 2025*

Good solid safe, but needs a handle due to the size and weight.

### ⭐⭐⭐⭐⭐ Good Safe to Keep Important Documents
*by W***N on February 8, 2026*

We needed a spare home safe and after shopping around, we bought this one. Probably too heavy for a handle so we can't complain. We placed some furniture sliders under the box to make it easier to slide on the floor. We hope we found an ideal hiding spot. Would be nice if the inside measured just over the side of a sheet of paper. The safe itself seems to be of high quality. We have a mid-size Sentry but needed to store additional documents.

### ⭐⭐⭐⭐ BEST BUY FROM AN ENGINEERING PERSPECTIVE
*by M***3 on March 16, 2019*

In my opinion this is a best buy for Fire and Flood, the only thing I would buy additional is some type of a dry to remove moisture especially if you are storing a hard drive or jewelry inside the safe and they may need to be replaced if you live in high humidity areas if you open the safe often during humid times. Any pouches should be for storing smaller items only, not the documents, they do not require an additional pouch. I purchased similar safes from SentrySafe and others before. Also with my 47 years of expertise as a consumer purchasing for myself as well as for the US Government, it is easy for me to separate the bull published in marketing materials. The 1550 degree Fahrenheit Fire Rating is nothing more than a known maximum temperature of a home fire where gasoline and Diesel Oil is not involved. Anything hotter is caused by a fire where gasoline and/or those accelerants are involved such as in an automobiles, on ships and tankers, or an oil refinery where the temperature would exceed well above 1700 degrees Fahrenheit in the first hour near the accelerant. I mention 1700 degrees Fahrenheit because some sellers claim this in their literature. Next is floodproof (submerged in Water) Flood Resistant (Rain) would require every aperture to be sealed with a rubber gasket and a marine type silicon lubricant tested to a specific depth, that I assure you is not typically done as I validate with Underwater Systems deployed in the Ocean by the US Navy and Oceanographic Research Groups such As Woods Hall on the East Coast and Scripps on the West Coast of the US. My Background: In my first 10 years after leaving the Military and my earning my engineering degrees, I worked as a Process Control Engineer, primarily performing destructive testing associated with Flood, Fire, Shock and Vibration, and Explosions of proto-type process control instrumentation and systems to validate engineering specifications to meet various commercial, government, and military specifications and requirements that would be used in extremely hazardous environments such as nuclear power and power plants, oil refineries, distilling plants, mills, US Navy ships and submarines. After that I have been an environmental systems engineer working for the Department of the Navy for the past 35 years for a variety of shipboard systems associated with Power, Weather, and Physical Oceanographic Systems deployed to Ocean depths of up to 10,000 meters ocean depth. That being said, the inside dimensions of this box are inaccurate for the depth, it is exactly 8-1/2 inches at the bottom and slightly increases as you come up, the sides are sloped downward by about 5-10 degrees. To satisfy my needs I purchased acordian file folders from Walmart and cut the open ends to exactly 8-1/2 inches. If you want -1/2 by 11 documents in a file folders that is your only choice for this box. not recommended putting documents in the box, will cause jamming problems and compromising the flood protection.
