Installed easily back in early December 2019 on a ring video doorbell circuit. Everything worked perfectly for the first 3 months and then it died. Tested the transformer with a multi-meter and no power output with confirmed power input. I expected it to last many years but since it did not I have to give this a 1 star. Don't waste your time with this transformer, the quality is not there.
