Love Ring devices and this latest doorbell is no exception. Video is clear, despite having a "fishbowl" effect to the lens. Two way audio works well with minimal delay (only a second or two) in the Ring app.
The disappointment was the Alexa integration. Alexa audio is Listen only, you can't talk back. The worst thing is the delay though. I have cable internet with 20mbps upload and 100mbps download, WiFi strength is 50-RSSI, which is a strong signal. Alexa takes 10 to 15 seconds to connect to Ring, by which time the alerting action is well passed. Worse than this, that 10 to 15 second delay persists during the entire session, meaning it is useless for real time viewing.
The camera/doorbell is great. Quality build and comes with everything you can imagine needing, even the drill bit, to mount it. The Alexa integration is pathetic though. Do not buy this for the Alexa integration. Buy it for all the other features.
