This is a fantastic Tevion Cassette converter. Now then, im sure many people of a certain age group will have treasured audio cassettes of their favourite music. Well, heres a simple solution to convert them to mp3 tracks. Virtually ALL the other devices require a software download of itunes or something similar and are a real fiddle, and the seller won't tell you. This needs NO SOFTWARE to work, you just plug a USB stick or an SD card in the slot, press record and start the tape going and in no time you have a perfect MP3 file. I can't enthuse enough about this unit, it knocks the silly fiddly ION units for six.
