Zhuanzhuan is really disgusting. I bought a backup phone from there above, but I never used it. After a month, I wanted to send it back to sell. I bought it for 5500, with an online appraisal of 5200, so I just sent it over. As a result, after inspection, it showed 3850. I was so angry that I immediately requested a return and decided not to sell it anymore. Customer service immediately called and said they could "help me apply for a little more." I asked her why the difference was so big between the initial estimate and the inspection, and she said it was "because the description didn't match the actual item."
