### ⭐⭐⭐⭐⭐ Good quality and easy to install.
*by E***E on 27 December 2025*

Good quality and easy to install.

### ⭐⭐⭐⭐⭐ Ideal for a bedroom
*by R***T on 10 April 2024*

Solidly built and good looking knob that was ideal for my daughters bedroom. Setup of passwords is easy if you follow the instructions. I understand having 2 passwords - one admin and one general use but this allows multiple passwords.. Not sure how that's useful! Once inside the room it acts as a normal knob to open but once out and closed you need a key or password to open - exactly what I wanted. The display for entering the pass code looks really neat and thankfully is not a cheap lcd screen. You won't even know the numbers are there until you put ur palm on it and it lights up. Overall very happy with this. Wish I had seen this earlier for other rooms. I got this installed by builder so cannot comment on the ease of installation but he did it pretty quickly and did not complain.
