Query: For Advanced Access Shoe Only

I'm writing this just in case some one makes the same dumb mistake i did. I typed in the search field for Canon 7D Microphone and this product came up. I read all the reviews and bought the item. i can confirm the build of the item is sturdier then ones i have actually seen and felt. however, i didn't realize that this item is for Canon's camcorders that have the "Advanced Access Shoe" only. Which my camera does not. I know i know.... i should of known better.
