Is there a difference between Haier refrigerator casarte bcd-80 1wdca and ex?

The suffix (EX) is added to the product code of casarte refrigerator, which indicates that this refrigerator is a prototype sold by Haier manufacturers to dealers, and it is a model for dealers to display. For the time being, regardless of whether the products with and without suffixes are of the same quality, refrigerators with suffix (EX) do not enjoy Haier 15-day free return policy after sale. When buying Haier refrigerator, you must pay more attention to the code of the products you send, and don't be deceived by unscrupulous merchants! In addition, when you call Haier's 4006999999 to inquire about the meaning of the suffix, the customer service will not tell you the true meaning of this code, but will only transfer you to the local after-sales service, and the local after-sales service will not directly answer this question. This behavior of not answering directly objectively condones the seller's black-box operation.
