Review: Nice stable voltage output - BTF makes a lot of great products for LED projects. I have never had an issue with anything I've purchased from them and I have a few hundred feet of different leds and several drivers now including this one, all have performed great. Even outdoors in less than ideal conditions(not recommended)
Review: Multi-strip wiring can cause fixable flicker with WLED - The power supply works great and added it to a single ESP32 controller with WLED (v0.14.0) in a 5 multi-strip configuration (325 leds total). Everything works great now but had to troubleshoot to get it there. Having 2 output nodes, I originally split the power from the power supply with one going to the controller and the other to the LED strips. Running 1 strip was fine but when I reached 3 strips or higher, I would get random flicker on the last 1-2 strips. (Last being defined as the last segment in WLED). Everything was fine if 1 strip was powered at a time. I resolved this by only running power from 1 node pair from the power supply to both the ESP32 controller and the LED lights. Power being split between all 6 devices (controller + 5 strips) from the power supply. LED power did not go through the controller, only data. That resolved the flickering issue, and all 5 strips now work perfectly. I'm not an electrician and don't know the root cause other than assuming that a power fluctuation occurred that was enough to create interference.

## Features
