Love the idea of being able to check who is at the door. On top of that the annual plan goes based on household not device number. However, this item is sure to also release a version 3 as this version still needs a little more tweaking. The sensor seems to be a bit off as others have pointed and the wifi connection only to this item seems to be spotty in my household. Another thing others have pointed out as well. I would give it 5 stars in an apparent but 4 or less in a larger home.
