Review on Player Build Speaker Recorder Supports Portable Audio & Video for MP3 & MP4 Players by Duane Ramos

The price was cheap and unfortunately the quality was just as bad. It charged once while I was downloading music to the device. I've used it in a stationary room a few times, but when it needed another charge (when I realized it was dead) I tried plugging it into a USB charger and the screen said it had no battery. I wanted to return it. but was told that I have to pay the UPS store to process my Revain return - that had never happened and I decided I wouldn't pay $6 to return a $20 item! I've been a mobile electronics engineer for most of my career, so I decided to look into the block problem. I carefully opened the small case and found TWO faulty wires to the battery. Although I was able to solder the wires "hair thick", the block continued to work with other logical errors - in the garbage.
