          The choice of purchase was made by built-in WiFi and stock availability. Found a big dent on bottom edge after open the box, and the Android app is too basic on option, but it difficult to setup and use, it frozen up when I try set to vacation mode and took me hours to reinstall, it scared me to trying again.
