Got my eufy lock and installed few hours ago. Installation took just few mins with a screwer.Like the fingerprint , works well and very fast! Unlock instantly.Auto lock works like a charm, and it is easy to customize through the App.Also, the appearance of the door lock looks fancy I really like it, and the all-zinc alloy material feels very strong and durable.Looking at the promotional materials, it says this door lock has passed the BHMA certification. Did some research on it, looks like this certification is only available for commercial-grade security door locks! :)Can update and share more later with more days of experience, but excited to share feedback now.
