Review on 12V WS2815 (WS2812B) LED Strip Light - 5M 300 Pixels, Aclorol Individual Addressable 5050 RGB LED Flex Tape, Waterproof IP65, Black PCB, DC 12V by Todd Lowry

Remember it's not 2815, it's WS 2812 B, these are two different things but apparently sold this company them as the same. too late to return, they were permanently installed at my house, i had many problems with their products, on one of the strip shows in the picture below, the light bar broke very weakly at the beginning, there were also power problems. It seems like a one-pixel-per-strip trigger is just weird. I've been doing pixel lighting for many years. This is the first time I order from this company and the last time.
