Review on Aclorol WS2812B 144 Pixels RGB LED Strip: Programmable Dream Color Lighting with 1M 144 LEDs, Weatherproof and Individually Addressable by Flavio Scarola

Very bright. Metal circuit board. When cut, the solder pads are small, but suitable for working. It comes with a flexible clear plastic cap coated with silicone on each end. The cover is a lot bigger than the strip so it kinda slides in. Each end has a pigtail with a standard connector for connecting multiple strips or connecting to a controller. The incoming cable has additional power and ground wires to add a power supply. The wire is quite long so if you want to join the strips together you will need coiled wire. I didn't need sealing so I just cut off the cover and soldered it together.
