I sent 12 cassette tapes to convert to CDs. I am amazed that what I received back was 30 discs each one 1 hour in length with the music
non stop on each disc. I am disappointed. I expected too much I guess.
The price was right and the cassettes were on a CD but,.... 1- hour of
non-stop music?!?!!!
Not worth it to me. I should have asked questions.
