Good quality and as photo
It works well and fulfills the intended purpose. The setup is not very easy if you don’t pay attention. I searched for a video on the internet that helped me. In the end, it works well.
Test was positive, works well
Overall product is fine, quick delivery. Only thing i don’t like is lag time between door bell button press and when it produce sound which is more than normal plus the product description does not mention chime only works with usb socket.
