I bought a device from Aliexpress that failed. I wrote to complain about it and received a reply, complete with a row of smileys expressing regret. I then decided to try fixing it myself, which seemed the simplest solution. The problem turned out to be more fixable than I had first expected and I succeeded in repairing it. I sent another message to the seller explaining this. In reply, I received a row of smileys blowing kisses at me! I don't think that would ever happen with Trade Me. Maybe they could learn something from the Chinese.
