Title: Instructions!
Review: The product is a long strip of darkened plastic rolled in paper. The goal is to get it to stick to the inside of the front window. The instructions to accomplish the task are clear and direct. The problem, as the other two gentlemen noted, is getting the strip to fit exactly. Patience counts but it works. Using the paper the plastic is rolled in as a template is an excellent idea.
