Had HappyTint do all the widows on the West side of my house - the basic reason being that I had no privacy ,anyone walking along the drive could see directly into my bedroom and sitting area so had to keep the blinds drawn all the time. I am very pleased with both the product and the Installer - a great deal of preparation was required as the window frames are 1970's solid metal - the Installer Jared was meticulous and thorough with prep,clean up and installation. I am thrilled with the degree of privacy I now have whilst enabling me to view my garden - I feel like I've been liberated from prison no longer needing to keep the blinds drawn plus the bonus of heat resistant and block out UV qualities > will mean a reduction in the use of aircon in the hot weather .
