[EX Q]: This unit was shipped promptly & as described by seller.
[EX A]: Good Review

[EX Q]: I am a fan of Dan Brown and his books, but "Angels & Demons" just didn't make it. There were many loose threads to be wrapped up as well which ended up left dangling. Why did Angels have the gift of telekinesis? Who was Mallozzi? What does he really know? Etc. etc. The big mystery at the end is never solved either, except for in Brown's own head (which got so tedious after a while).
[EX A]: Bad review

[EX Q]: My son loves puzzles and was excited to receive the puzzle. However, we were very dissapointed with this puzzle. The "board" is made of cheap paper like puzzle pieces but really big pieces. This isn't even a regular board. It came loose from shipping and had creases in it. The bottom piece fell apart within 2 days when I picked it up off my son's floor.
