What Ultraloq U-Bolt Pro owners think

Most owners who chime in say they like the U-Bolt Pro and lean on it daily without complaint, several specifically praising the fingerprint reader and the fact that it keeps working locally even without a WiFi bridge or during a network outage. The recurring frustration sits on the smart-home side: Z-Wave support gets called severely limited, promised SmartThings integration hasn't materialized, Keymaster entities are missing, and Alexa routines can't drive the unlock. A smaller group ran into flat-out reliability failures, batteries dying within hours of a fresh swap or the lock simply acting up from the start. Anyone shopping this for a serious home-automation setup should expect to work around the platform gaps rather than plug and play.
