## Customer Reviews

### ⭐⭐⭐⭐⭐ Mains powered doorbell
*by J***S on 6 June 2025*

Mains doorbell. Good price.

### ⭐⭐⭐⭐⭐ Exactly as described
*by A***E on 15 February 2024*

This bell was purchased to replace one which was installed when we purchased our apartment 10 years ago. Although the box is smaller than the previous one, it was easy to install and looks neat. Good sound too.

### ⭐⭐⭐⭐ Not a high enough voltage for Ring
*by G***L on 13 October 2021*

I had hoped that the transformer in this device might be enough (12v or more) to power a ring doorbell, but unfortunately it's about 6V measured open circuit, and reduces significantly when there is a load (presumably the resistance of the bell itself) Anyway - unfortunately it doesn't work for a Ring device so I've had to buy a separate power supply / bell. (https://www.amazon.co.uk/gp/product/B001GJVSLE for the transformer, it took me a while to find one that was wall mounted!)
