## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great, just make sure it is for a matching doorbell
*by A***O on June 15, 2025*

This works completely great and was used to replace a buzzing unit from the 70s. I would just ensure that you are connecting this to a Broan/NuTone doorbell and not get your hopes up on using this for smart doorbells

### ⭐⭐⭐⭐⭐ Works great, exact replacement of dead C905 transformer.
