Magicezy hairline crack repair stuff?

[KevO]

Got one of those regular marketing e-mails from an online chandlery today. It was pushing a product called MagicEzy hairline fix.... a product that supposedly uses nano tech to fill and repair hairline cracks. Anyone used it? Does it work or is it another snake oil product?

There's a thread about it somewhere with before and after photos.

Does improve very small cracks I recall but limited success otherwise.
