These light/alarm clocks are so pretty! I have an iPhone, WiFi, but somewhat hesitant to purchase in case I have difficulty with the setup instructions, and then maybe not even using the alarm clock due to that, but almost willing to try. After watching/listening to this video, I'm leaning toward the Arkenstone instead of the Sunstone.
My only tip for set up if you are having trouble is to switch off your phone data when connecting the WiFi credentials using the app. Otherwise it should be straight forward
