There are a lot of window film brands on the market. Some are good and some are..... not so good. How can you tell the difference when everybody in the window film business sells "the best" window film products? Just ask them. While many are proud of the brand they carry chances are they carry that brand for a reason. Whether it is price, installation ease or brand name recognition. But, in the end it all comes down to this.
Over the past 10 years there have been a lot of foreign window film brands introduced in the U.S. Some with "Americanized" names. While I am not suggesting that these products are inferior, I am suggesting that if you should ever have a warranty concern.... GOOD LUCK!
I have personally worked with a number of window film brands in my years in the business. What I have found is that most American manufacturers are quick to respond to warranty concerns. Most, if not all even cover the glass that the film is installed on. This is not true with some of the foreign brands. Be sure to read the warranty carefully before buying. Just because it has a catchy name, doesn't necessarily make it the best choice.
There are a lot of good products made in the USA. Most are fairly equal in quality. Nobody really has better product than the next. Even the products from a major manufacturer like 3M and the guys that claim their film "chemically bonds" to the glass. (This stuff is a PAIN to get off the glass when it fails)
My view is as long as you stick with a product made in the USA you are more often than not going to be pleased with the film and the warranty. But, if it comes from Korea or India.... be careful.
Our American Standard Window Films and Sun Gard films are made right here in the USA for your peace of mind.
