Customer reviews on Amazon

  • 1 star5%5%

Customer feedback reports positive experiences with app usability, ease of connection, fingerprint recognition and general functionality, while battery life and Wi-Fi reliability are mixed. Some customers report good battery life, while others say batteries last less than two weeks, and connectivity problems are also mentioned. That variation matters for a lock whose advertised remote controls and status checks depend on connectivity. The overall rating distribution leans positive, but does not resolve these practical concerns.

Positive themes

  • Customers report an intuitive app and positive experiences with fingerprint recognition and functionality.

Negative themes

  • Customer feedback includes reports of Wi-Fi connectivity problems and unusually short battery life.

Mixed feedback

  • Battery life receives both favorable and unfavorable feedback. Wi-Fi connectivity is also described inconsistently.
