This forum is not a place for personal insults. If he insulted your lights, insult his if you must, but not him personally.
Nobody here is a diplomat; however, the point made, that the lights you are selling are not from or for the Japanese market, is valid. Whether you believe him, or me, or neither, please refrain from personal insults.
For what it's worth, even knowing what I've said about the lights, your price is IMO reasonable. Good luck with the sale and enjoy the forum.
