Query: A Very Poor Product

This is a very poor version of this type product. I purchased two online after my local home improvement stores stopped carrying a different version. The ones in the store were heavy, this one is light as a feather, which is why it will not stay in place. I have tried heavy duty two sided tape, heavy duty glue, and duct tape, and nothing will work.
