Google Nest x Yale Lock
Score: 78/100
Level Bolt
Score: 85/100Rankings

The Level Bolt is a retrofit smart lock that installs inside an existing deadbolt, preserving the original hardware and aesthetic appearance of the door. It offers multiple access methods and high security standards but suffers from short battery life and the need for additional hubs. It is best suited for design-conscious homeowners who want smart technology without visible hardware changes.

The Google Nest x Yale Lock is a high-security smart deadbolt designed for Google Nest ecosystem users, featuring Grade 2 certification and IP65 weatherproofing. Its primary limitation is the lack of compatibility with Alexa or Apple HomeKit, and it does not support voice unlocking. It is best suited for homeowners already invested in the Nest secure system who want seamless alarm disarming upon entry.
