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.

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.

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 TIGERKING 17.6 Cubic Feet Heavy Duty Safe is built for those needing significant security and storage for their valuables. Constructed with 75mm thick explosion-proof steel doors and reinforced with multiple high-strength locking bolts, this safe promises robust protection against theft.

Weighing in at 235 pounds, the safe is quite difficult to move, reducing the risk of theft by relocation. Additionally, the anchoring options allow you to secure it to a wall, enhancing its anti-theft capability. A notable feature is the anti-theft alarm system that activates on tampering attempts or incorrect entries, providing an audible deterrent.

However, it's important to note that this safe lacks fire and water resistance, potentially limiting its capacity to protect against natural disasters. The removable wheels, included for ease of transport, should be removed post-installation to prevent misuse, albeit they aren't covered under warranty. Another consideration is the 30% restocking fee for returns not related to quality issues, which could be a drawback if the safe doesn't meet expectations. Ideal for home, office, or hotel use, this safe is backed by a one-year warranty and a satisfactory customer review rating. It's a solid choice for those who prioritize anti-theft features and need a large storage capacity, but it may not be suitable for those seeking fire or water protection.
