Needed this for my Camera doorbell alarm system. It was easy to install and works perfectly since my other cord had a short.

Very easy to install wire up the doorbell contacts on the back and plug into outlet. Has worked from the day until now with no problems or issues.

This was imperative for us to have so that we could have a smart thermostat since we didn’t have a C wire. My husband installed a new outlet next to the furnace and then ran the wiring for this through the wall to it. It was a great, inexpensive and hidden fix so we could have what we wanted!

Purchased one September 2023, didn’t last six months. For the price you expect better quality and reliability.
