It took me some time to get them to work how I wanted them to. I have 7 in my kitchen and need them to act as one. The App is clunky... But after messing about for an hour I found how to group them and then control all as one...They are brighter than expected on white...and you get from very warm to very cool temp...
I've not yet messed with the 'Scenes' but I'm sure they will be fun...like I said, the main thing was getting them saved as a group.
