This was the quick/easy/inexpensive fix I needed. For years we had been dealing with my dog barking at everything that walked by our house. We thought about switching out the glass in our front door to one with an internal shade but kept putting it off due to price. When I found this option I thought why not give it a try. It is working out really well so far. I did take the advice of other reviews and used a soap & water mix before applying the cling.
