The dynamic lights have a good color spectrum, the length for the price paid is good and the effects are good, too. Also good is that the music recognition is built in, and although it has less rhythm scenes which are built-in than the main NanoLeaf rhythm module, they are sufficient. Only downside is maybe, that the controller, where the microphone and the power button are, gets warmer than I expected. And it stays warm, even when the lights are off. App sync works, and editing and previewing scenes works well, just sometimes it seems to not work as planned, but it’s okay.
