Review on 🔥 BTF LIGHTING WS2812B Heatsink - 10mm x 3mm (WS2811 Compatible) by Aquarium Biggs

Fantastic! They are small, about the size of a coin, so some dexterity is required to work with them. I use a helping hand to hold them for soldering and that's not a problem. They work great! So far I have controlled them with Raspberry Pi 3, Arduino Uno and Nano. In all three cases they were great, bright, pleasant in color and very responsive. I bought a 5V 15A PSU to power them, but I also connected them directly to the 5V rail of my EVGA G2 1300W PSU and they worked with no issues . Keep in mind that all 100 at full brightness draws a lot of amps, too much for your USB port so an AC adapter is a must. Soldering is pretty easy. They are small but there are enough contact pads, 6 in total, 2 for 5V, 2 for ground and 2 for data in and data out. That's 600 solder points for the entire batch! I've had the most success with 20 AWG solid wire. I tried using the 4-pin stranded wire I had for regular RGB LEDs, but it became brittle and snapped at the solder joints if touched too hard. I also used 3-pin 18AWG wire, but this is stranded wire and can be tricky to solder. The single core cable was the easiest for me. I enjoy it very much and will buy many more!
