Bests & Worsts Reviews from Amazon

I waited months to receive this item, as I loved the concept. First problem: my wall is textured stucco and the flimsy mounting frame will not stay rigid on an uneven surface. I spent hours making foam pads, and even then the unit made erratic contact with the base. Second problem: after finally leveling the frame and getting it to work, I added a second user to the app. It made the first user disconnect. I played around with deleting and reinstalling on our two iPhones and never got both to work. Third problem: on the 3rd night after installing, the unit decided to ring the doorbell incessantly; only going outside and pushing the doorbell button made it stop. After an hour or so, it did it over again. After the third episode of phantom ringing, I took it off the wall. Fourth problem: I described these issues to DoorBot customer service and waited a week to return the unit to Amazon, but got no answer. I returned it, and now, a month later, have still not heard from DoorBot. This product is in, at best, the alpha stage, and should never have been released. Oh, one other thing... the alert on the phone is severely delayed from real time, making this of limited practical use, particularly if trying to talk to someone at the door.
