Which Clip for me and kids?

Thank you, we have actually just bought a Fire to take instead of our smart phones, so great minds think alike! However I don’t want the children to have any screen time at all - not even making playlists, editing photos etc, and that is why I wanted them to have MP3 players rather than smart phones or tablets. Still wondering if anyone thinks one of the Sandisk players is better than the others - think I am going for the Clip Sport if no one has an opinion!
