i lacquered and perma-soaked mine, and it still fell apart.

And other people have permasoaked the synthetic aoto with no problems at all. And I've read just as many people talk about how it broke right in half on them.
I'd say the most careful was to use the stone is as a splash-n-go. And honestly I'd be careful of getting an X-large size cause it could break under its own size and weight. Unfortunately, it's really a hit or miss kind of stone. But it's a damn good stone, so I'll have no regrets buying another one after another one.
