At about 6¼ inches tall and 3¼ inches wide, it’s compact enough to be portable but still large enough to hold multiple keys securely. The shackle fits most common door knob styles, allowing easy mounting on various doors or fixtures. One drawback is that it only holds up to five keys, which might be limiting if you have many keys to secure. Also, while it’s built for outdoor use, extreme weather or tampering could still pose challenges, so placement matters.

The package includes five lock boxes, which is great for managing several properties or sharing among a team. The product comes with a limited lifetime warranty, backing its reliability.
