Review on 🔌 16V, 30VA Doorbell Transformer Compatible with Ring Pro & Nest Hello by Joshua Douglas

The threaded mounting ring was not properly secured to the transformer body, allowing it to rotate freely when attempting to thread a nut onto it. The nut that came with it didn't fit the threads properly so it was easy to slide onto and off the threaded mounting ring. I had to find a slightly smaller nut to fit the threads and I had to press it against the box to keep the threaded locking ring from turning when tightening the nut onto the threads. The transformer works but it would be quick and a simple replacement was a long and painful process. This transformer also does not have a built-in resettable circuit breaker. I should have spent more time learning about transformers.
