Question: 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.

Answer: Negative

Question: My daughter loves her blocks. She will get them all out and look at each one until she finds her favorite. She likes to shake them and see what each one does. These are cute little blocks that have hours of imaginative playtime inside. They also have blunt corners, so no sharp edges like wood blocks for the safety of smaller children. The fact that they have the letters of the alphabet and a corresponding object inside makes them a great learning tool even for older tots. We have really enjoyed these and recommend them to our friends.

Answer: Positive
