The Maxell UR-90 were on sale for 2 € per pack of five, so I couldn't say no.
I'm not dead serious about that cassette tape deck. Just mildly serious enough for wanting to make it work again and have some fun recording silly stuff from my MP3 library. So I can make friends suffer, erm, listen to it.
And to show cassette tapes sound better than what most people think of them nowadays, if handled with proper recording equipment and noise reduction.
