Tint USA of Charlotte installed a window tint to all the ground floor windows of my home, both for privacy and to protect from the worst of the sun and glare. It's such a subtle difference, but the light coming through my windows now is much softer, less bright and harsh and the glare on the tv is nearly gone! I know in the long run my electric bills will go down and my furniture and floors will last longer. A great investment! The installer was extremely courteous, patient and meticulous with the install! Very pleased with the service I received from Tint USA of Charlotte!
