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: I bought this first alert CO alarm for my home in Wisconsin.When I started to read the instructions I found that this product is not UL list! How can a safety item like this not be UL listed.I did some research and found out first alert changed testing labs to save a few bucks and do not use the most well known UL. What's up with that...So I returned this CO and purchased the Kidde KN-COB-DP-H Plug-In Carbon Monoxide Alarm. The Kidde unit cost less too, so I saved a few dollars! Always pays to READ THE FINE PRINT.

A: Negative

Q: I thought this was going to be a good movie. Rotten Tomatoes gave it a 95%. It's the worst highly rated movie I've ever seen. My girlfriend and I kept saying "WTF?" the entire time we watched it. It made very little sense. The Road Warrior is much, much better.
