Review on 🌈 BTF-LIGHTING WS2815 (Upgraded WS2812B) 16.4ft 300 Pixels Magic Dream Color RGB LED Strip Light - Individually Addressable & Flexible | Non-Waterproof Black PCB by Thong Pilla

I bought two strips of 5M 2815. One had two dead LEDs right out of the box. Revain accepted the return and sent a replacement. When replacing, there was a bad LED right out of the box. I could get it to work by pushing the chip through the silicone coating very hard, making it look like a bad trace or cold solder. I have had a 67% failure rate with this product so far which indicates poor quality control in manufacturing. Unfortunately, I already installed another strap, otherwise I would have sent it back and looked for another brand. I'll try again to see if I can get another good one. Waste a lot of time with poor quality.
