I've seen it, bought it, and like it. It's a Ring Flight plot that's logical and quite pretty to watch: a borrowed ring disappears in the hands very, very cleanly, only to be found strung on the performer's necklace.
Caveats: it takes a fair amount of practice to master, and it has some tricky angles. You'll find a lot of discussion about this at themagiccafe.com (just do a search on Flight 204).
