Query: If you're lucky & get a good one it's fine

I bought two of these. One has been ok but the second one would spit out any tape you fed it. Returned it immediately and got another one that did exactly the same thing. By then it was too late to return to the store so it's sitting on a shelf as a paperweight. So one of three worked. On another subject, the remote is awful - so I use an old "Tower" remote I got at Goodwill.
