Here is my experience with Joybuy and this model. I ordered the RP-HD10 ($69.99 at the time) on October 1, 2018 (EDT). I received it on October 16, 2018. The right speaker stopped working on October 19; see my post at https://www.head-fi.org/threads/panasonic-rp-hd10-a-serious-contender.752736/page-14#post-14550759. I submitted a dispute on October 23 through the jd.com website. Here is the text of my request: "I received this item on October 16, 2018 and treated it with care.The right speaker stopped working a few days after receipt. Note: I would welcome the opportunity of receiving a working replacement of the same product, but I noticed that it is now out of stock. If you do have a working replacement, I would prefer to receive a replacement than a refund." After a couple of days, I asked for an update on my request by email; a reply came to be patient. The request was rejected with the following online message on October 26: "Dear customer, we are so sorry for all the trouble caused. In order to solve your problem effectively, it will be highly appreciated if you could provide a clear video evidence which shows your problem (Please upload the video to Google drive and send us the link). Thank you." I saw the online reply on November 1 and sent a video on the same day. Very early this morning (November 2) I received an email with the following text: "Regarding your order: ... , thank you for your reply. But from the video you provided, we can't understand the problem clearly. Would you please explain it or provided another video which could shows your problem." I replied with: "Thank you for following up promptly. The problem is simple: the right speaker does not work. The video is intended to show that sound comes out only from the left speaker. I am not sure that I can explain the problem more clearly than this, but please ask if you need more detail." I am withholding judgement as I wait for a resolution.
