In the FWIW category, these WeHonest signals have been operating on a display shelf 15/7 for 2 1/2 years. They have worked perfectly.
One note, the board would not hold the brightness setting once power was removed. With a help request here on the forum, @stan2004 suggested changing the 0 ohm resistor for a 1k ohm at that location. Worked exactly as he said. 👍
