I received a quick response from Darksucks to confirm my address. They are sending a replacement for the acknowledged timing problem, and a return label for the defective light. Cheers to them! I don't own any of their Alpha/Delta lights, but do own a few 4/7s lights.I have this same issue in a recently bought Mini MK-III. I emailed Darksucks when I first got it, and they sent me a video of how to get into programming mode - not my issue at all. I just want to change output levels, and "a timing issue too short for humans to achieve" is right on the money. We'll see what response I get this time.
