This is an old question. lol... If I said 99% like the other Chinese suppliers do,will you order from me?
I don't want a sale speech I want the truth that come from your testing. I will be more piased if you say 99% and after testing it is 85% then if you say directly 85% and it's confirmed by test facility. (Numbers are fictional)
I don't live in minipony land. I prefers a good clear compromise then a dirty lie
