The SentrySafe Fireproof and Waterproof Gray Steel Home Safe is designed to offer robust protection for your valuables and important documents. Its alloy steel construction and 6 live-locking bolts ensure durability and security, while the pry-resistant hinge bar adds an extra layer of defense. The digital keypad lock allows you to set your own combination, providing personalized security along with a secondary locking key for added safety.

This safe excels in fire resistance, enduring up to 1 hour at 1700°F and staying secure even after a 15-foot drop during a fire. Additionally, it offers 24-hour water protection in water up to 8 inches deep, making it highly reliable in flood conditions. With a sizable 2.05 cubic feet capacity, it's spacious enough to store documents, money, and other valuables effectively. The interior lighting is a convenient feature, making it easier to access items in low light conditions.

However, the safe's substantial weight of 124.8 pounds can be a drawback for some users, especially if frequent relocation is necessary. It includes bolt-down hardware, allowing secure floor or wall mounting, but this might require professional installation for optimal security. The medium-gray finish is aesthetically pleasing, blending well with home interiors. The reliance on batteries for the digital keypad may be a minor inconvenience as four AA batteries are required but not included. Additionally, some users might find its size a bit bulky, requiring ample space for placement. Despite these minor drawbacks, the SentrySafe SFW205GQC is a solid choice for those seeking heavy-duty protection for their valuable items.

The SentrySafe Waterproof and Fireproof Alloy Steel Digital Safe Box is a robust option for those seeking to protect valuables and important documents. With a UL classification for fire resistance, it can endure high temperatures for up to an hour, which is excellent for safeguarding irreplaceable items during a fire. Its waterproof feature adds another layer of security, having been verified to withstand flooding for 24 hours at a depth of 8 inches, making it suitable for various disaster scenarios.

The safe's locking mechanism includes a digital keypad, which allows users to set their own combination, and a secondary key for added security. It is constructed from durable alloy steel, featuring four live-locking bolts and a pry-resistant hinge, ensuring strong protection against unauthorized access. 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.

The ADIMO Safe is a robust choice for those seeking a heavy-duty safe, particularly appealing for home and office use. Constructed from reinforced alloy steel, it offers commendable durability against tampering and drilling attempts. The safe is designed with three thick locking bolts, enhancing security, and comes with two expansion screw holes for secure mounting, meeting the anchoring criteria well.

One of its strengths is the dual security access system, which uses a combination of a digital keypad and keys. This feature is reassuring for users who may forget passwords, as the master and emergency keys offer backup access. Moreover, its intelligent dual alarm system adds an extra layer of security by alerting you of unauthorized access attempts.

The safe includes a fireproof and waterproof money bag, providing additional protection for valuables such as cash, jewelry, and important documents. However, it's worth noting that the safe itself does not claim water resistance, so the bag is an essential component for water protection. Inside, the ADIMO Safe is designed with a removable shelf, allowing flexibility in storage and organization, and a built-in LED light for easy access to contents. The built-in lockbox is a thoughtful addition for organizing and further securing valuables.

With dimensions of 19.6"D x 12.2"W x 15"H and a weight of 46 pounds, the safe is reasonably sized for personal use, though some may find it slightly bulky for smaller spaces. Its 2.1 cubic feet capacity should suffice for typical home and small office needs. The ADIMO Safe delivers well in terms of security and flexibility, and potential buyers should consider its best suited for environments where the lack of external water resistance is not a significant risk.
