Several users noted that it provided additional peace of mind when away from home, making access control flexible and secure.

On the downside, some users encountered issues with connectivity, especially when trying to control the lock via Wi-Fi.

Users frequently highlight the robust security features, particularly the combination of fingerprint, passcode, and app control. The lock also offers backup keys and an emergency power port, which adds to its reliability. Many felt reassured by the multi-layered protection, making it a solid choice for both homes and businesses.

A few buyers expressed concern over the need for a Wi-Fi gateway for remote control, which they felt diminished the overall convenience. While the lock itself is secure, these users would have preferred a fully self-contained system without additional purchases or setup requirements.

Wi-Fi Gateway Requirement

70%

30%

The Wi-Fi gateway, while an additional purchase, provides greater flexibility for remote access, making it easier to manage entry from anywhere. It can be a helpful tool for those who need to monitor or control the lock when they’re away, adding another layer of convenience.

However, a significant number of users expressed dissatisfaction with this added requirement. Many felt that the gateway should have been included in the original package, especially given the price of the lock. The extra purchase and setup process are seen as a hassle for users expecting a plug-and-play experience.

Voice Control Integration

20%

Voice control integration with Alexa and Google Assistant is a popular feature, adding an extra layer of convenience for users who prefer hands-free operation. This is especially useful for busy households or offices where quick, voice-activated access is necessary.

Backup Keys & IC Cards

84%

The inclusion of two backup keys and three IC cards is highly appreciated, especially for users who prefer having multiple access options. The cards are especially useful for people with children or those who need to provide access to other family members without relying solely on the fingerprint sensor.

The combination of fingerprint recognition, app control, and physical backup options makes it a well-rounded choice for those seeking a reliable, modern lock at a competitive price.

Some buyers feel that the overall cost could have been reduced if the Wi-Fi gateway and additional IC cards were included as part of the package. While the lock is a solid investment, the extra accessories and required purchases make it less of an all-in-one solution.
