Great app

Put on Spotify

Works Great

Bought the controller. Had to install a QR code reader to find the app. Badly named app, searching fails. Connected strip lights to the controller. Sync'd up with no problems. Was able to control LED strip lights using color wheel. However, tried using music feature, it failed to "dance the LEDs" to music. Figured it was the app, then realized the device does not connect like a speaker, but has tiny hole with hidden mic to pick up the music to modulate the LEDs. App works and has quick response.
