One of the standout features is the lifetime warranty, offering peace of mind for your investment. On the downside, the 1.63-pound weight might be a bit heavy for some users, and the mechanical code lock may not be as convenient as electronic options.

The larger storage capacity is a plus, accommodating multiple items easily. The Keybox 3 also includes two shackle sizes to fit different handles and knobs securely. Additionally, the app allows you to track access times, providing extra security and peace of mind. However, the Keybox 3 requires four AAA batteries, which are not included, and the extra feature of real-time notifications requires purchasing the Bridge separately. While the setup and use of the app are straightforward, it might be complicated for those who are not tech-savvy.

Users have found it relatively easy to set up and use, appreciating its large capacity and sturdy build. However, it’s worth noting that while it is weather-resistant, it may not be fully waterproof, so ensuring it’s placed in a sheltered location could be prudent.
