Good for the first 12/18 months, now App Crashes CONSTANTLY. When it does decide to open the sound cuts in & out every 2 seconds, so does mic, making it impossible to understand the person at the door, and they can't understand me either. It records for 2 long when there's no one in shot, and doesn't record for long enough when there is.! I'm Disabled, and I bought this to make my life a little bit easier.. quite the opposite.. when it worked Properly it was very helpful.. now it's awful 🤬
