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)

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.

It worked great for about a year and a half
The output was a barely adjustable around 4.9 +/- 0.05 volts and after about a year it started to vary between 7.8 volts to 8.1 volts and cannot be adjusted. I was using this to power devices that need regulated 5 volts and that is why I bought this supply. Unfortunately it didnt last long.

Great transformer but
Nice enough and does what it says. Only issue is the 110v/220v switch is near impossible to change without removing the cover, which breaks the warranty seal. Why are these shipped in the US with it set to 220v by default? Also, they don't have a user manual plus none online. Wish I knew what the voltage fine tune feature did and how to use it.

Works for LED strip DIY project
I used this power supply for a 5V LED strip and had a few problems at first, but the customer service team was able to help me out and get the issues resolved. I did not need my project to look pretty since all of my controllers were going to be hidden away, so the size and shape of the power supply made it easy for me to place wherever it needed to go. Additionally, this power supply made no noise at all which allowed for no distractions from the lights.
