This was very easy to apply, but would be easier with 2 people. I did have a little trouble getting all the bubbles out. For the most part, the bubbles were minimal. This  window film has lowered the temperature in my front room SO VERY much. With prices of everything going up, this has saved me so much money with cooling my house. I also absolutely love that you can see out in the daytime without letting people look right in your home. So worth the money!
