Review on 🎛️ ALITOVE Bluetooth Controller for Addressable LEDs - iOS Android App, Wireless Remote Control, DC 5V~12V, Compatible with SK6812, SK6812-RGBW, WS2812, SM16703, Dream Color, Programmable RGB LED Strip Pixel by Cyndy Segotta

So far I have had all the problems with it because of the application. But since it is necessary for the operation of the LEDs connected to the controller, I think it is justified. It's not immediately apparent that the controller is NOT paired to your phone, only in the app. The first 20 times I opened the app, there was no Bluetooth scan at the top. It was just blank even though I knew BT was active because I kept checking and trying to manually pair the controller. I even emailed the manufacturer about the pairing issue (no replies after 3 days btw) and then the app finally decided the phone has bluetooth. Connected and working great. Application templates are still in their infancy. Re-pairing after closing the app is annoying. Problem with this app, it could have been great but for the price I can't complain too loudly.
