Irresponsible buyer. Buyer accepted price before meetup. During meetup, buyer complained my item was an old version and googled on the spot stating new version was worth more to purchase. Buyer short-changed me by offering $15 lower than accepted price. It was unacceptable. I have stated the model number and took photo of the Xiaomi box together with the item. Buyer could have googled the item before agreeing on the price. It was such a disappointment.
