Score: 88/100Rankings
The Vaultek MX Series is a high-capacity smart handgun safe designed for storing up to eight handguns with modular interior configurations. It features rugged 14-gauge steel construction and advanced ViSN connectivity for remote monitoring, though it requires separate battery purchases. It is best suited for users needing quick bedside or closet access to multiple firearms with smart security features.

The SentrySafe SFW123DSB is a medium-sized fireproof and waterproof safe featuring a mechanical dial combination for reliable, battery-free access. Its main trade-off is the slower access time compared to digital locks and the heavy weight. It is ideal for users who prioritize certified fire and water protection without relying on electronics.
