The headlights themselves are decent quality, the app is good and the Alexa compatibility is good, but they're too easy to reset if you use a physical switch. The lights revert to their default configuration, which is bright white and flashes in settings mode. In this mode, they don't interact with the application because they want to be added again. Luckily in most cases the blinking stops and I can change the configuration without re-adding the lights, but I haven't figured out why or when they stop blinking. This is very annoying and seems to happen quite often even though we don't keep turning the lights on and off. All you need to reset the light is on-off-on-off-on. Not sure what time it should be as it seems there could be hours between them and it still resets from time to time. It would be better harder to get into reset mode.
