Purchased together with the $850 installation service. The technician arrived on time and did a neat job fitting the C-grade lock. The scrambled PIN code gives great privacy when neighbours walk past. Excellent value for money.
T. C. Shum
Fast dispatch and customer support quickly confirmed the door thickness requirements before ordering. App notifications work instantly when the doorbell rings, and Cantonese voice navigation is great for the family.

The lift-to-lock handle is smooth and feels very sturdy. Interior safety switch prevents my dog from accidentally opening the door from inside. Quick dispatch from BBE, well packaged.

買之前問過CS門厚問題，覆得好快好清晰。附送卡片俾工人姐姐用啱啱好，自己用指紋幾秒入屋，曜石黑外型好match我屋企隻大門。

Generating temporary passcodes on the app for visiting relatives is very practical. Good value overall.
