I live in a house that’s over 100 years old so some of the windows are odd sizes and drafty. Originally I ordered 3 Indow window inserts for my dining room to try them out. I was so impressed with their appearance and effectiveness at insulating and reducing sound that I decided to order more. Recently I ordered another 9 Indow window units for my living room, bedrooms, bathroom, and kitchen. Both of the orders went very smoothly. They arrived well packaged and in perfect condition. I have already installed all of them and just in time as Chicago and most of the midwest has just been hit by a winter storm and blizzard with below freezing temperatures and 8-12 inches of snow. I couldn’t be happier they look fantastic as well as being practical and functional. My home is so much warmer and quieter now that they have been installed. Indow’s pricing was great and they gave me discounts as a returning customer and for bulk purchasing. Customer service, instructions and follow up were all excellent. Such a wonderful company and product.
