I'm very disappointed in this product. For some bizarre reason they have provided the printable PDFs oriented in landscape orientation (so they are wide but short), rather than the traditional portrait orientation. Which is extra weird, because if you buy the actual, hardcover screen, it's in portrait orientation! And look, not many people have folders that unfold in a horizontal orientation, so I'm not sure how they think you're going to use these.
And keep in mind, I'm reviewing the newest release - they give you printable files, it's not just the giant and nearly unprintable ones it looks like (from reviews below) they originally had. The printouts are also tough to read, the charts are confusing...overall, annoyed I spent the money. Don't be me, save your cash!
