Review on ALITOVE WS2812B 5m/16.4ft Dream Color LED Strip Light - 300 Pixels, 🌈 Programmable, Waterproof, Flexible, IP65, Black PCB - Ideal for Home Bedroom Bar Decor Lighting by Carmen Rosario

I received what is clearly new factory packaging after returning a completely dead filament (see below) - this worked straight out of the bag, all LEDs work in all colors. The tape looks good, is easy to solder and is as bright as any other 2812B tape I've used (ie: blindingly bright at full power). 60 LEDs per meter is quite dense and gives a very even light on the surface. .Alitove contacted me when I was sending the dead strand back to Amazon and immediately offered to send a new one. is working. If you connect another chain of NeoPixels to the same pin and 5V power supply, they will show normal test patterns. Judging by the oscilloscope, the data signal never reaches the Data Out pin of the first LED - the signal is present at its input pin. I tried cutting off a few pieces hoping it was just a bad chip but I couldn't find a single working chip, they all behaved the same and didn't display or pass any data. Some of them turned green when 5V was applied. If I return for a refund I will try a different brand.
