the seller is actually very nice. It's so nice that I think I have never seen such a nice seller in the past several years.

Today, when I was about to continue the negotiations about the details, like which post office they want to use, who to pay the fee, etc. One thing I care a lot about is when the replacement shipping will be shipped. If they only ship out the replacement once they got my current unit, that's unacceptable. It will at least cost another 7 to 10 days before I can get the current one I ordered. However, they sent a tracking number before I started typing, and later, I found out that is the replacement unit they sent out to me. My unit is not even being picked up.

I hope we can have more sellers like this one in China.
