Review on 🎵 BTF-LIGHTING WS2812B WS2811 1903 Bluetooth Controller with Dual Signal Output Ports for LED Module Pixel Strip Light Andriod iOS APP /3 Keys Button/RF Remote Control, Music SP601E Built-in Microphone by Paul Stephenson

The controller is buggy, often freezes on a certain lighting scheme and does not respond to attempts to change the lighting scheme from the application. Waiting a day or so eventually resolves the issue, but then it only works for a while before getting stuck again. I ordered a replacement that has the same issues. It's a shame because the lighting circuitry is actually amazing, especially some of the sonically reactive ones, and I love that it's plug and play, no soldering required, just needs a better quality code or something.
