Setup was easy once the app recognized my wifi.  That took a couple of tries so if you are having issues and getting no results for found wifis, dont fret.  Just wait a bit and try again later.  Once the wifi was found the app walks you through the set up in a very easy to understand manner.  Since I only have the one bulb I cant say if setting a up a circuit would be harder.  So far the CYNC by GE bulb has been easy and reliable to use, Ive had issues in the past with wifi enabled lights not staying connected to the wifi but this is still solid after a week of use.  

In the app it is easy to select a color and brightness.   Thank you CYNC by GE for making it easy to set moods!
