I am happy that I now have several rooms in my home that are noise sanctuaries. I am very sensitive to noise and intermittent dog and child noise outside was stressful for me. I added Indows to my bedroom, exercise room, and family room and I love that I can enjoy those rooms in peace. I no longer hear birds or dogs outside in the mornings and the neighbor children behind me are seen and not heard. Road noise has also been greatly reduced in my bedroom. Thank you Indow for increasing my quality of life! I only rated 4 stars out of 5 because of all the work I had to do myself in measuring and installing them. I wished the company had someone to install them for us, but they turned out great. My wood blinds were able to install over the top of them and the Indows are invisibly doing their job for me. It was definitely an expense and some work, but worth it in the end for the added peace and privacy I feel in my home. It was much easier to install the smaller bedroom windows than the larger family room windows, so if you order multiple sizes, start on the smaller ones first.
