Bests & Worsts Reviews from Amazon

I bought this for my parents. We installed it exactly as told and in the middle of the night the bell began ringing. My dad disconnected it at the bell at 3:30 in the morning. For the next three weeks we did everything the manufacturer told us to do. This included going back the door bell manufacturer and getting copies of the original door bell install diagrams and providing pictures of all components for the door bell. After nearly a month we got and email that said the door bell is not compatible. so sorry! Due to the time it took to let us know and agony of it all, Amazon will no longer take it back as a return. Ring is horrible to deal with. To not know it was not complicated to know from the original email we sent them that their system NEVER work with this type of chime. Now i have a bell I cannot return. Perhaps they know the exact length of time to hold you out on their emails and tech support so you fall a few days over their return limit. I'll definitely remember that one!
