Totally worth the cost!
I wish I knew about this sooner! It's simple and does exactly what it says it will do! I have 3 small dogs who jump at the windows to see outside and some of my windowsills show plenty of wear because of that. I purchased a custom size for our window and it came quickly exactly the measurement I needed. i highly recommend this product and plan to purchase a few more.
