Stable voltage for doorbells.
Good quality product. Stable 24VAC voltage. Size is bigger than my expectation and heavier too. But works well. I use it for Ring doorbell.

Poor quality getting very hot even with no load
The transformer getting very hot and likely will damage soon due to excessive heat. Manufacturer used less number of coils turns to save money which is causing this issue. PS. Connected to 220v supply using the black and orange wires. It may blast and make a risk of fire. Not recommended….

It gets very hot with a fry smell once connected to the Ring doorbell for 2 minutes. It can cause a fire. I have disconnected immediately and will dispose.
