Useless. Randomly decides when it wants to show you a video of what transpired. Lack of controllability. (Can't set sensitivity for motion, notifications come through EVERY TIME a car or person passed by. Pinch to zoom feature NEVER works! Don't bother with this thing. Return it and get a competitor's brand instead. This doorbell was a waste of time and money! They're going to reply with "get Nest Aware and you can control the sensitivity." #CashGrabApp!
