Great price, very fast shipping, A++ seller.

It looked like a very good product, so I had high expectations and placed an order. Order date: August 17, 2026 Shipment completion date: August 17, 2026 Product receipt date: August 27, 2026 It took 10 days from ordering to delivery. It's okay. However, the product that arrived was in a terrible condition. There was a paper box product inside a plastic bag. It was so badly handled that it was dented, torn, and a complete mess. I am very disappointed that such a delicate digital device was packaged and sent in this way. Moreover, it seems like it was opened from the bottom. The tape on the top also appears to have been reattached, as if it were two pieces stuck together. When I opened the box, there was no damage inside the messy box, which was a blessing. However, there is no manual. No matter how hard I search, I can't find it. And when the CD is played, it does not play smoothly but instead produces a rattling sound. I played the original CD, but it rattled and spun around, making me very anxious. The video isn't uploading. And The device operation notification sound is too loud and has a rough tone. It's so quiet that you almost don't want to turn it on at night. I wish I could turn off the operation notification sound. Even the smallest volume level is too loud. You can never listen while sleeping. The design is nice and the sound quality is decent, but why are there issues with the notification sounds or volume levels? I don't know if it's ridiculously loud or just rough. Please turn it off or make it possible to adjust the volume. This is the case with most Chinese products. I looked for the manual on the manufacturer's website, but it was not there. If you have a manual, please scan it and send it to me.
