The cases are sturdy manufactured walls not too thin, not dented or the like.
The DVDs / CDs can be easily install and just as easily removed again.
The film is not as thin as other makes and breaks easily, but glued properly and sufficiently "thick" to prevent tearing.
The only (small) drawback is the closure of the cases, which did not work right away with me, but is easily doable with a bit of flair.
I think it's just matter of habit, therefore no rating trigger.
