Q: Do not buy this toy. If you are given this toy as a gift, return it for store credit. This is a flimsly and poorly designed stack of platic and paper. The secret door doesn't work, the elevator doesn't slide and toys get stuck in there. The suggested 10" batman doesn't work with the zip line, bungee or even the elevator. The add says "Using new adhesive technology, you can set up the Batcave on just about any wall" so they want us to glue this thing on to a wall.Please don't buy this toy.

A: Negative

Q: An extremely helpful gem on a complex subject of second century religious authority and textual use. For anyone serious about this period and the interelation of cultures, this book is essential. Is it complex and detailed? Of course, it must be to argue the point. Should you buy it? Yes, unless you want to keep running back to the library. I write this only after thoroughly disagreeing with the review above.

A: Positive

Q: I am starting my fifth month of pregnancy and bought the pillow to get used to sleeping on my sides. At first, I was scared of the size and concerned it might bother my husband and my little dog that sleeps next to me. I tried it and absolutely loved it. My husband cuddles up next to it and my little dog uses the pillow as well and sleeps in it with me. We joke around about the size, but it is really comfortable. It is a must have during pregnancy.

A:
Positive
