WM-EX612 Back Cover
The back cover of the WM-EX612 has a large and generous clear window so that you can see the tape hubs and the remaining tape. This is a much more sensible design than the other models I have seen.
A simple design is better sometimes.

Here is another view of the player. Interestingly, it has two small slide switches at the back as well.
