## Customer Reviews

### ⭐⭐⭐⭐⭐ Mains powered doorbell
*by  on Reviewed in the United Kingdom 6 June 2025*

Mains doorbell. Good price.

### ⭐⭐⭐⭐⭐ agb
*by  on Reviewed in the United Kingdom 11 June 2026*

excellent

### ⭐⭐⭐⭐ Not a high enough voltage for Ring
*by  on Reviewed in the United Kingdom 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!)
