Review on HKBAYI 4M WS2812B 5050 SMD Built-in WS2811 IC Black Board LED Strip Lights - 240 LED 240 Pixel Matrix (Non-Waterproof) by Brent Rosecrans

Great product, used in several places, my favorite is the fully custom LEDs in my computer case. Looks absolutely amazing. Use them with esp8266 using WiFi connections to host a web page that controls the led strip mode. The whole thing is powered by a 5V rail from the Molex connector, when the PC goes to sleep the whole thing loses power. The system uses 92 LEDs. The picture does NOT convey that justice, nor are fingerprints really visible. I'll try to get some sort of polished version on Github soon. I also used LEDs for my projector room. ambient lighting. This works very well. If I could complain about them it would be the libraries for them, they are quite intensive for Arduino but with esp8266 it's not that big of a problem and won't be a problem when I upgrade the system to esp32
