The interior space is decent, with a 1.23 cubic foot capacity, allowing for storage of essential items like documents, USBs, and small valuables.

However, some drawbacks should be considered. Weighing in at approximately 86.69 pounds, it can be heavy and cumbersome to move, particularly if you need to relocate it. The need for four AAA batteries for operation may also be a minor inconvenience, especially since they are not included. Additionally, while its fire and water resistance ratings are impressive, it may not be suitable for larger items due to its size limitations.

However, the safe has some drawbacks. At 217 pounds, it is quite heavy, which can make installation and relocation difficult. While it does come with bolt-down hardware for anchoring, its weight might be more than some users want to handle. Additionally, it requires AA batteries for operation, which could be a concern during power outages or if the batteries run out unexpectedly. This safe is best suited for individuals seeking robust protection for their valuables against fire and water damage, but potential buyers should consider its size and weight along with its locking mechanism before purchase.

Additionally, some users may prefer a digital locking mechanism over a dial combination, as it may offer quicker access. While the fixed combination is secure, it could be less convenient if the code is forgotten.
