The main problem for the three stars is the connectivity between the camera and the iOS app – it keeps dropping the connection, and when I try to reconnect, it will not do so. Turn the camera off and back on, start and stop the app, over and over until after four or five attempts, it reconnects. VERY HIGH FIDDLE-FACTOR!
