Customers say
Customers find the transformer easy to install and appreciate its quality, with one noting it’s stronger than doorbell wire. The functionality and noise level receive mixed feedback – while some say it works well with Ring Doorbells and makes no noise, others report it doesn’t work with Ring devices and makes buzzing sounds.

Used with RING doorbell
I’ve used this for my ring doorbell for the past 12 months with no issues and no faffing charging the battery every few weeks. Definitely a must buy if you don’t have pre wires for a doorbell. Installed myself as all you have to do is attach the two wires to the two screws at the back. Tracked the wire up above the door and plugged into the hallway. Simples.
