SBD and I recently completed a trade and it was an excellent transaction. My end of the trade (Yuin OK2s) was shipped to me very quickly, and arrived in the exact condition SBD described them. SBD was also very quick to respond to my questions, and the level of communication during the transaction was fantastic. I'm enjoying my new earbuds, and would buy, sell, or trade with SBD again any time.
I sold Shawn a pair of RE252 earphones. Communication with him was great, and he was quick at payment. We could complete the transaction in about 1 hour, with prompt replies from each side. I wouldn't hesitate to deal with him again.
