We don't use the products and don't know exactly how various products feel, it's like how one type of potato chip has different flavors, some people like barbecue flavor and some people like tomato flavor. There are always individual differences,I don't like it when people ask me what is the strongest product, in fact if you like tomato flavored chips you will feel that any other specialty chips are not to your liking, at this moment in time you only like that one, we can only analyze the strengths and weaknesses in terms of objective data, it doesn't represent subjective feelings. As for what customers need what products like what feeling, this is their freedom!
