Screwed in the bulb, after a second or two, it went into setup mode. Opened up Smart Life and almost immediately is showed up. No need for the manufacturer app. Took all of a minute to set it up. Finally a smart product that works the way it should. The colors are nice and true. All the features seem to work flawlessly. Have not added it to Alexa yet, but never had a problem adding a Home Life device to Alexa. Expect that to go smoothly as well.
