WESIRI 241 LEDs 9 Rings WS2812B 5050 RGB LED Ring Lamp Light Individually Addressable Full Dream Color DC5V with Mini Controller

I received my first set of led's, and they were DOA...I believe the packaging was the reason, no packing. Amazon quickly replaced and shipped in a box with packing. They worked beautifully, but then the 8 led ring was flickering...it seemed it was at the weld of the control wire. I reached out to Wesiri, and they responded quickly and offered to ship me a new replacement. I can't say enough, about exceptional customer service...it's very rare anymore, but not with Wesiri. Kudos, keep up the great work!

I was worried that theywould not work after snaping them apart. They were easy to separate and these are the same size pixels that are on the 16x16 matrix. Some of the rings out there have smaller pixels want the same price for less than half the fixels and small rings. They all work great. The wires are terrible alloys on all the china made neopixels. I always remove and discard their poor excuse for wire. It fets how. I/d buy it again. and remove the wires again too. I'd rather they knock a couple bucks off and don't solder any wires on.

I was very excited about finally working with the WS2812B rings. I had hoped to put this into a computer case project I'm commissioned to build. However, after the first set I received my hopes dwindled. The first ring set was only partially bad. 99.59% bad. Nothing lit up at first. I suspected the controller so I tested that on two other RGBLED strips and it worked fine. I started to connect the controller to each ring individually and only got the center LED to work. Another ring partially lit wrong and then sparked. That set went back. The second ring set was just DOA. Now, this set is going back. This would have been a perfect 5 stars if it worked. It would have been an excellent value and I would have recommended this to anyone wanting to play with RGBLEDs like Neopixels. With this failure rate, make sure you can return it if you decide to try it.

these are really nice and bright

Fired it up, all LEDs lit. It's a standard 3-wire addressable ws2812. Have not tried programming my own pattern(s) yet. (Arduino code on Teensy with Octo board.) It is pretty bright with all those LEDS (241) concentrated into a six-inch circle. Not melt-my-mind amazing, but it is kinda' cool if you like LEDs. Each circle has it's own plugs, unit could be separated into individual LED rings if you so wanted. Functions as expected, no negatives to note.Comes with a little program module that takes 5v/ground (2 wires only) and outputs a data signal with 2 or 3 patterns, can toggle some colors on those. Has standard ws2812 3-wire plug for output. (5v/ground/data.) Patterns looks like the video.
