Hi. Been a while since I updated here. If you remember my sad tale, I had purchased a used DTR1, which after a while if use just stopped working. Didn't charge, didn't turn on, nada. I for in touch with Anson (many thanks to F700), who had me send it to someone in California (shipping to China was prohibitively expensive). They couldn't do anything with my unit, and sent me another, which was just as dead as the one I sent there. I let them know, and they sent another, which turned on, but didn't play music. Anson was ready to replace it again, but I realized I had loaded a new SD card, figured trying my old one (which worked in my original player until it died) made sense before trying again. Sure enough, the player worked fine, the card was defective. So I'm back in action. I really have to give incredible thanks and kudos to Anson; the service was so above and beyond the call of duty it's amazing! (he actually owed more no service at all). Loving the player, I'm a happy camper!
