We love the idea of Ring, so much so that we bought the doorbell, several cameras, and the security system. This review is primarily for the doorbell. The motion detector often doesn’t alert or record until several seconds after someone has passed through the motion detection range. Yet somehow it alerts us to cars driving down the street. Additionally, the app rarely (20% tops) allows us to open the doorbell alert. We click on the alert immediately, with full cell service, and the app opens to a black screen with the answer/Hangup buttons and an indication it is loading, but never loads. Therefore, we cannot use it to see who is ringing the bell and speak to them, which defeats our primary purpose. It’s really disappointing that so many users have complaints like this and they are not being resolved. We do like the interface for the security system in the app, it’s really easy to use.
