Query: FM Transmitter useless. Loses position if battery changed. Badly designed.

The specifications of this player looked like it was the perfect MP3 player at an excellent price. Resume, FM transmitter and 2GB.The resume works, sort of, as long as you dont pull out the battery. And then it will tell you - no files found. You have to play with it a little bit, move between voice and music to make it find the files. Didn't Trekstor have a Quality Assurance department?The FM transmitter doesn't work without headphones attached. Now, why would I want an FM transmitter, if I wanted to attach wires? And even then, the quality is bad.It wont play in order unless you have the files numbers in the front of the file name, not at the end as files are usually named.
