I bought this board to convert 12 volts to 9 volts and it worked great initially. About a week later it stopped working and was only outputting 12 volts. The adjustment knob does not work. I've always shot it very lightly and slowly. I have 5 others that work great. When I contacted DROK about this issue, they gave me a task to do 42 steps to get it working. This is a physical issue with the adjustment knob. They have to stand on their products. Sometimes they work, sometimes they don't.
