The order of color channels (RGB/RGB) is wrong either on the controller or on the strip (I'm not sure), which makes some scenes look weird. For example, the candle light flickers between red and magenta instead of red and yellow, since the green channel is actually blue. The app SceneX won't connect to the controller (although it is visible on bluetooth) so I can't change any settings. Otherwise, the strip is of high quality, the connectors are solid. The only thing that bothers me is that I can't use the app and I can't set the order or channels.
Sorry for the bad feedback! I had to restart my phone, and then I was able to connect to the controller and set the correct order of color channels! Unfortunatelly there is no longer an option to change the feedback on Aliexpress, but I would give 5 stars ★★★★★
Works great as advertised. Two thumbs up!
