The glass I'm applying this to is on an 8-foot door and I need someone else to help, SO..... I haven't installed this yet. However, I can tell you it looks like a quality product. The instructions are very straightforward, but I'm not sure how I'm going to get it cut straight or applied straight without help. Also, I had to buy a small, felted squeegee to use when applying the decal. That was not included in the package. I uploaded the tools needed list and instructions so you can decide for yourself if it's worth it.
