I already send the replacement set to China and when they send me the  replacement set I'll send it back to them. In the mid of it there is absolutely nothing I could do.

I can choose to bug them everyday.

But it won't change anything. They already say maybe we'll send out by December.

Just for your info I ordered yb659 since October and now still got no stock so who am I to complain.

I did my part and if that is not enough and moderater think I can do better please advise. But to fork out my own unit and then receive a replacement set without box is not possible. Customer who ask hoe the warranty works I also got explain to them er will help you send to China and when they send us the replacement set we will send it back to you.

If you think i'm scamming then there is nothing I could say because I'd did my part and there is no reason for me getting the blame of China yoobao didn't do their part.

You got it wrong. One to One exchange means if it's spoil and under warranty will exchange a new one for you. Not bring to repair and give you a recon set.

One to One exchange on the spot means like you say.

Your feedback is all about first purchase. No doubt your response to any buyer is fast but the main topic here is the warranty claim.

What you wrote in your thread is under your responsibility, not Yoobao. So the consumers is dealing with you, not Yoobao. You are misleading the consumers.
