As it turns out, they advised me against returning it as shipping back to China is quite expensive. But they offered to send me the proper one at price, minus the shipping charge. So, it's on it's way.
I don't understand why it is more expensive to ship into China than it is to ship out of China. But, it is. $5 to ship from there to here, (USA, East Coast), over $20 to ship back. Ridiculous.
