I have used this type of product before and found it quite good. For any reviewers dismayed at the lack of a color display, consider how prisms work. I have many hanging prisms both in the garden and at home. It's wonderful to capture the brief incantations of this pop of color. That's how it is with this product. I used this to block the view of the building right outside my window, but to the side the view isn't blocked. When the sun is lower on the horizon, the window application shows its colors, but only from the unblocked side. If you look directly at the sun, the colors show up everywhere on a sunny day. I like the template the way it is and it was easy to install. (Just spray a small amount of water on the window before applying).
