Has anyone ever used the ready-made pearls/dragees by Global Sugar Art?

Specifically these: http://www.globalsugarart.com/product.php?id=18527&name=White%20Dragees-8MM

You're supposed to just toss them in pearl dust and stick them onto your cake.. I just want to make sure it's a good product (i.e. the pearls won't crumble on me or something) Any feedback? And what do you usually use to make them stick -- tylo glue or plain water?
