We’ve been very satisfied with the product. We had it installed in every window in our downtown residence. The East facing views were problematic with the sunrise. The early morning heat buildup and fading on our furniture was a real issue. The 3M Prestige Film has really done wonders so our energy consumption will be far greater and lifespan of the furniture will be extended. It is also more soothing on our eyes looking over the great Columbus skyline both in the morning and evening hours. We’ve recommended the product to our friends and neighbors.
