When it comes to size, this document box has a capacity of 0.65 cubic feet, making it suitable for storing essential items like passports, social security cards, and birth certificates. The built-in straps provide organization, helping you keep documents easily accessible. The locking mechanism utilizes a key lock, offering basic security, but it may not be as high-tech as some might prefer, especially for those looking for electronic or biometric options.

Portability can be a concern, given its weight of nearly 39 pounds. While it is designed to be floor-mounted, its weight may limit how easily you can move it when needed. The material feels sturdy, but some users might find the design a bit bulky, especially if space is a consideration. The one-year limited warranty provides additional peace of mind for buyers.

Additionally, the combination lock adds a crucial layer of security to prevent unauthorized access.
