If you bought one of these and it flickers, here's why. Instead of returning it, I decided to open it up and explore. I immediately noticed that Hot, Neutral and Ground were never soldered to the motherboard. I applied the right amount of solder and the arrow works perfectly, no more flickering. I don't recommend doing what I did as I'm a 27 year old electrician with some electronics experience. I would return the item for a replacement.
