Device itself:
The cheapest thing you can produce in Asia anyway. Longer than the guarantee I really give the device is not now. All plastic which just goes and really not a good feel.
Sound:
Despite the very simple case, I have yet the expectation that the tone no zoom or background noise is at least played. Unfortunately, both are exactly the case. There is a clear sums available and unfortunately the tape does not run quietly so the sound always a knock is heard.
Have directly cassette and cables exchanged in order to exclude other sources of error. Unfortunately without success. Even the power source I've changed.
Will the device return in the hope that is the replacement device better.
For the software I can not say anything because I have not a rational player never made me only to the digitizing.
