Like many others, I bought a Nest Hello and had to wire my doorbell because the previous owner didn't have one. The location where my doorbell is is in a very difficult spot to catch the wire so I looked for alternatives. I came across this item and it works exactly as described and my doorbell is fully functional and working great. I only use the Google Home Mini as a chime, which came in handy too. I have recommended this item to several who have been in the same predicament as me.
