Ultraloq U-Bolt
Score: 88/100Rankings

The Ultraloq U-Bolt Pro is a high-security, hub-free smart lock featuring built-in WiFi and an 8-in-1 entry system. Its main trade-off is potentially reduced battery life due to the power demands of continuous WiFi connectivity. It is best suited for tech-savvy homeowners who want robust security and versatile access methods without additional hardware.

The August Home Smart Lock Pro is a versatile retrofit lock that installs over existing deadbolts, offering broad smart home integration via Z-Wave and a separate WiFi bridge. Its main drawback is the reliance on an additional hub for remote features and the lack of modern entry methods like fingerprint scanning. It is ideal for users with Z-Wave hubs who want to retain their physical keys.
