I got my copy about three days ago (just before the Easter weekend started). It's very good. It's like Keep on the Borderlands, but with multiple small dungeons rather than the one large one. There are many plot hooks that can lead beyond the module, which is a nice touch.
The map tries to be both a player map and a CK map - I think this was not a good decision, although it's not a killer. As the CK, I like to see a more definitive map - it helps me keep things straight in my mind.
All in all, it's very good. If my party weren't 10th level, I'd run this module as a starting point for a campaign.
