Bests & Worsts Reviews from Amazon

Bought a refurbished Ring doorbell from Amazon. Installed and it worked on and off for a week. Then without warning it completely shut down. Called Ring Support and found out that the MAC address was not provisioned correctly, resulting in a non-functioning unit. Ring Support did immediately ship out a brand new unit (not refurbished) which is not working properly. 5 stars to Amazon and Ring Support for fixing the issue, but the initial product gets 1 star.
