Review on 🌈 RGBZONE DC5-24V Mini 21 Key RF Remote Controller for WS2811 WS2812B LED Dream Color Strip Light - Effortless Remote Control for Dynamic LED Lighting by Vanessa Lopez

Revised from 1 star to 3, may fall back depending on lifespan or if they catch fire. After I cut my first WS2812b length from 5m to just under 1m (about 25 LEDs) the strand worked! Hooray! It's probably worth trying a secondary power supply in parallel for more LEDs, but that's it. The description says they can drive 1024 pixels, but mine couldn't drive 150. It's possible they are powering the circuit from a secondary power supply, but I haven't checked. Review. Ordered three 21 button versions and none of them seem to work other than illuminating the filament with a fixed/unchanging RBG rainbow (color changing through multiple LEDs and duplicating multiple times along the filament). It looks like the remote doesn't affect the controller in any way. Even tried a new battery. I am using a WS2812b LED from BTR. The thread works great with the Adafruit 5V sphere with Neopixel libraries.
