whats the full name and make of the Zen for an ebay search?
Innous Zen media player. I got lucky with the one I bought it's a two TB version but it's quite old, 2015 I think however it went back to Innuous last year and had the OS upgraded to the latest version, according to the seller.
There's an even older version of the Zen, it's not called Innous though can't recall the name of it now maybe someone will post it.
