Score: 88/100
Level Bolt
Score: 85/100Rankings
The ULTRALOQ U-Bolt is a versatile smart deadbolt offering high security with ANSI Grade 1 certification and Matter-over-Thread compatibility. It features a large fingerprint capacity and IP65 weatherproofing, making it durable for outdoor use. However, remote access capabilities are limited without purchasing an additional bridge.
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.
