Once I received the item I ordered, I quickly realized that the main feature I bought it for was nothing more then a piece of casa.com's false description of the item. Not only was the main feature I bought it for nothing more then a fraudulent claim by casa.com, but they also sent me a Kidde brand item when I specifically ordered a GE product. So not only does casa.com not know the difference in manufacturers, but they also use false advertising to sell their products.
