Here's my story:
I ordered my first pair some time ago and after 2 weeks, they were still a no show. Yangdu was very responsive to my panicked emails and after the two weeks had passed, she sent me replacement blades. The very next day, I come home to a triangle box and a face of "no f***ing way" came over me. Long story short, they came after a good while, I bought one of the replacements off of Auntie and shipped the other back. The lesson: be patient no matter how painful.
If I had to say anything about the ordeal; getting a tracking number would be nice.
