Instructions are incomplete and confusing
It takes a lot of patience and trial and error to figure out how this app works. It refers to different “gear numbers” with no explanation as to what this is referring. Once you adjust the time settings to not overpower you with scent, what do you do next ? Press the power button such that it turns green, but then it reads out power “off” or should you leave it red and then it reads power “on”? OMG—just keep trying different options and hope it works.
