My wife listened to little thinkers while growing up and her family gifted us a set of CDs that had been recorded from their original tapes. The quality wasn't very good and most of the discs skipped, so we were thrilled to find this website. I had a question before we ordered this USB and Jim got back to me right away and was extremely friendly and helpful. The quality on the adventures we've listened to so far has been fantastic! We highly recommend the full set!
