Fassacouche ? Any tried it.

Hi guys, first post. My names Mark been appreciating the advice and posts in here for a while so thanks fellas. I’m looking to see if anyone’s used Fassacouche before? It’s supposedly same as Parex/Weber but a bit cheaper. I’ve been offered it at £8.95 a £30kg bag (inc vat) and just wondered if anyone’s had experience with it?
