These inserts are so easy to install and look fabulous. They weigh nothing and are crystal clear. We used to avoid one room in our house because it was so cold, but not any longer. The customer service has been top notch as well. I made a mistake in my order and Scott, Eric and Jessica went out of their way to fix the issue quickly. I wish all companies were this responsive to their customers! Great product

I'm very happy with this. I live in central Texas. With my IR gun, I measured the outside temperature of the window at 105 degrees. Without the inserts (and without turning on the air conditioning with the window under direct sunlight in the late morning), I measured the inside temperature of the window at 101 degrees. When I put the inserts into the window and waited a few days, under the same conditions (direct sunlight in the late morning), I measured the inside temperature of the window at 92 degrees - nearly a 10 degree difference. I also measured the inside temperature of the wall right next to the window at 83 degrees (again, with no air conditioning running). The inserts make a huge difference with these single-pane windows. Obviously they're not going to match the insulation of the wall, but they do insulate very effectively compared to having nothing there at all or compared to replacing your windows entirely.

Excellent customer service.

I ordered 7 one piece inserts with one being slightly larger. Unfortunately when received the largest insert had been shipped as a split insert. I contacted by email on Sunday and problem was resolved Monday. Went above and beyond to correct the problem.

We ordered Window Inserts for 5 of our extra large European-type windows. The windows add a lot of charm to our home but do not keep us cool in summer or warm in winter. My only regret with this order is that I didn't do it sooner!

It took us a couple days to get all of the inserts in place but once we had one room done there was a noticeable difference right away! It has really helped keep our home cool this summer compared to last summer.

We had an issue with our original order and Eric responded to us quickly and called the same day he got my email - on a saturday. He took care of the problem and was great to work with. We really appreciated his customer service and LOVE the product!

I work for a University and our windows are like paper and we have COLD winters. This product has made a HUGE difference in our offices being much warmer. Our windows are very irregular in size due to being an old building, but the inserts fit pretty good considering (definitely not a manufacturer issue, but our old building). While the inserts are flexible, they are not flimsy and I found rather easy to get in and out. The gentleman that I worked with was fantastic about double checking my measurements, etc. and do everything he could to make sure we were satisfied. Great product and team!
