I just needed to digitize some old family cassette. It could not have been easier. My Windows laptop recognized the device as a microphone so I could use the built-in Windows voice recorder to capture the sound.
It comes with a dvd to perform some post processing but I don’t have a DVD player anymore. They should just allow you to download the software. I could find a trial version online which worked for the once-off function I needed.
I have not tried music, so cant give an opinion, but if you just want to convert something sentimental or nostalgic then it is perfect at the price
