I received my windows last week and therefore I installed them over the weekend. They are fantastic! I watched the installation video again and followed it to the T and the windows went in perfectly and look great! Super product! I wish I purchased these years ago instead of one of your competitors, which have all literally fallen apart due to the heat. The magnetic system is the way to go. Now my only problem is that I have to replace the other 18 windows that I have. I will be in touch.
