Opinion on the Diamond fortress adventure

[danir]

Hi,
I'm looking to buy a new adventure for my party and this one has caught my eye (diamond fortress - http://www.kenzerco.com/product_info.php?cPath=25_42&products_id=232)
Anyone played it or read and can give me his opinion (sadly, review section is offline atm)?

Thanks,
and If you know any other good adventure for circa 11th level, let me know

The Diamond Fortress is a module designed for 4-6
characters of 11th-13th level. The module is set near
a large town famous for its frontier spirit, and takes
place in a fortress full of magic and terrible monsters.
In the module the PCs must destroy the magic that
holds the fortress on the Material Plane before it can
be used as a staging point by the demonic forces contained
within to ravage the town and the surrounding
lands.

That's from the introduction.

I've read it (I bought the PDF version) and am currently considering borrowing several ideas from it for an adventure in my next campaign. Overall I like the adventure.
