Here's a review that I found regarding Terial Magic ... interesting.

I've seen the folding pen demonstrated, but didn't really see the advantage in it.
However, if the demo had been more focused to an end use, perhaps it would have made more sense.
Disappointing that the store offering the class does not have the Seam Align that you need.
This really annoys me, when an LQS gives a supply list ... and then does not have the product!
Seems like very poor planning on their part.
Or maybe even lack of interest and commitment to their customers/students!
