We got our windows about 10 days ago and they are fantastic. I have been given your name out like crazy so if you start getting a lot order from Alpena Michigan, you can say Zen Fitness. They are fantastic. We are no longer freezing. Yeah they fit perfect easy to use. I put them in myself. Just wanted to tell you how wonderful there. Thank you very much and you guys have a wonderful day.

The window inserts are fantastic,
I ordered for a screened in porch. Now I can use the space on days when it is not freezing. They were easy to insert & the owners were super helpful as we were unsure of our measurements & called several times with questions. I highly recommend them, they look great & very affordable. Thank you for this wonderful product, good quality & good looking!

Thank you so much for our windowinserts we have used them in our porch screens and it has made a wonderful outdoor lounge to sit in during the winter months with sweaters and blankets.....we love them and it makes all the difference in our freezing Canadian winters.

Also thank you for your wonderful service and alleving my worries and concerns. [First time making a purchase from a nonbox store...

Just want to tell you how pleased we are with the new inserts. They arrived promptly and well protected in the shipping box.
It was a piece of cake to place these into the windows and within a 1/2 hr. all 13 were in. We get a constant westerly breeze on the front of the house and had been experiencing a lot of cold drafts. The plastic storm windows with the double-sided sticky tape were a hassle to put in and looked terrible. The drafts are gone the inserts are almost invisible and we're sure we'll be saving on heating fuel during the winter. You have a great product. Happy Holidays. Ours is sure to be warm and cozy.

Received my latest utility bill it has gone down about 10 dollars so far so good. The whole house has the inserts and they work great. As some of you know Iowa is cold and windy most of the time in the winter months. So if you have a draft coming through your windows purchase this product really works.

I bought the inserts (six so far) for all the windows in the bedrooms. They have resolved long standing problems with my single pane windows. I have them inserted between 1 inch to 4 inches from the outside window panes. I am going to purchase more for the basement windows. The cost for all six inserts was less than what it would cost to replace ONE window.
Thank you for your product and quick delivery.

The inserts function exactly as advertised, and they earn very high marks, along with your excellent customer service.

Many thanks!

What a great product and company! I bought 9 inserts in Oct of 2015. I live in cold northern Vermont, and a house with very good insulation. These inserts are 100^% as advertised. Great looking, fit, quality of frame and plastic are Top Notch. Always have great interaction with customer service! Thanks for providing a great solution.

Love, love, love my Window Inserts! I have 2 large drafty old windows in my historic home. For years I have wanted to get storm windows but the cost was prohibitive. These inserts installed in a snap and they look great. Eric and his team are the BEST! Their customer service is second to none. They are very responsive and helpful. And my order was in my house in a week from my placing my order!! Thank you!

These are a fantastic product. The custom fitting according to my measurements is absolutely PERFECT.
It seals my drafty sunroom which has eight storm two-pane windows and nothing else for insulation. I put these in and presto! No more draft. It allows the sun to heat up the room nicely.
I made an error in measurements for one window, and Jessica solved my problem immediately. Not only that, she came up with a two-insert solution for the storm door, and saved me a lot of money for the item AND the shipping.
I really love it when things exceed my expectations. Both the window inserts and the customer service do just that.
Thank you Windowonserts!

I ordered and installed 21 inserts in a 113-year-old county Museum and another 15 in a restored railroad station of equal age as the Museum. The savings for both buildings have been in the hundreds if not thousands of dollars. The installation was quick and easy. Only one has been wrong and it was my error, as I forgot the double-hung window was not split in the middle. I have recommended this company and their product to many people.

Good afternoon! We received all our inserts and got them installed last night. Thank you again, we already felt a difference in the temperature of the room within minutes of them going in! Your company does amazing work, and thanks so much for the replacement for the dented one, We will keep it as backup.

Arrived this morning
I put them in and they are PERFECT
I want to THANK YOU for a job WELL DONE

I just wanted to follow up with you regarding our purchase of six inserts a year ago for our screened porch. What an awesome, affordable product you make. The inserts are easy to install and make a significant difference by keeping the wind and snow outside. We were immediately pleased but wondered how the inserts might hold up. They look like they did when they first arrived. And, bonus points, the box they were shipped in make an excellent storage container for off-season. Wish we could go back to our initial review and update with more glowing words. We recommend these inserts to folks on a regular basis.

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 bought these back in 2005 and I’m still using them, they work as well today as when I bought them! These are a great product!

The folks here know their stuff and remember you months later. A real personal touch which is nice.

I purchased several dozen inserts for my home and they really do their job nicely. They trap the heat, remove drafts, and protect wood frames from humidifier moisture condensation. They install faster and look better than "plastic wrap" style window coverings. It's also significantly less expensive than replacing windows.

I'm very pleased with the product, the results, and the service. Highly recommended for cold Maine winters.

I received the window today. It fit like a glove, I could feel a reduction of heat coming thru the window right after I put them up. I am going to add 4 more windows tomorrow. This is an excellent product and very reasonably priced. I am very happy with them .

No More Drafts! No More Drafts! No more Drafts! The very first thing I noticed once I installed all 23 Inserts was that the drafts were gone. I also realized my windows have been costing me over the years. I got the inserts last night and had them all installed in about an hour, it was very easy to install them. It was cool last night so I could really tell the difference once I got all the inserts in. Today was warm 78°, and with temps like that my house is usually up above 78° before 3pm, today it never went over 76°. I already know these inserts are going to save me money. The packing was above standard, there is no way any of the inserts could be damaged unless something catastrophic happened. The inserts are a quality built item. I don't foresee any quality issues. The polyvinyl has insulating properties as well, because the first thing my wife noticed is she can't hear the outside noise she usually hears in the morning. There is a true measurable temp difference between the windows alone and the windows with the insert installed. My windows were between 65°-68° last night before I installed the inserts, about 15 min after I installed the inserts I measured the temp again and it was 73° using an infrared thermometer. The AC/ Heat was not on. That's significant. Well this is only my first impression. I will write another review once we get into the dead of winter. I expect I will be equally as impressed. I'll also report savings as I have tracked my energy use for about 5 years so it will be pretty accurate.

These windows are awesome. we live in a duplex that was built in the 1600 and added on in 1843. We went through one of the coldest winters on record last year and was expecting huge heating bills. To our surprise, our bills were less expensive than the previous year and the house never had that chill you feel in old houses. the inserts stopped the drafts and kept the house a consistent temp all winter. Liked them so much we are ordering 16 more for the rental and feel confident the tenants will be comfortable. Thank you for this simple effective product.

Window inserts was a pleasure to work with.
They addressed all our concerns and did what ever they could to make sure we were happy with our order.
The conversations with their staff was always pleasant.
Great company to do business with.

We just received our 6 kitchen window inserts and they look fantastic, fit perfectly and absolutely have stopped all of the cold draft coming in through the windows. The ordering process was easy, they kept us notified of our order status and they shipped and arrived quickly and very well packaged. We have a 119 year old home we just purchased and decided to try these out before purchasing window inserts for the entire home. I have to be honest, we were skeptical about the claims but not any longer. We had a winter storm after placing these inserts, the temp was 17 and the winds were gusting at 60mph. I can't think of more extreme conditions to try these out in and not a single kitchen drape was moving from drafts coming in and they are remarkably clear. We will be outfitting the rest of the home, 40+ windows! but this is way less expensive than new custom windows plus we can retain and enjoy the beauty of the original windows and woodwork. I cannot recommend highly enough!!!!

I ordered WindowInserts for our museum. The building is a 108 year old single family home that has been converted to our County Historical Museum. We put the WindowInserts on 17 windows, some very large. They fit beautifully. The first month that we can record showed a 30% drop in our heating and electrical bills.The building is very tight and draft free. We are in Michigan where every little bit of help to seal a old building is welcomed.

I just received my order and popped them into the windows! They are all perfect and I feel warmer already! Thank you so much for calling me to clarify the split order. I appreciate your product and your customer service!

Will definitely be ordering again.

I love our windowinserts. You exceeded my expectations.
Jessica went above and beyond with excellent customer service. Our inserts arrived BEFORE the promised date. The windowinserts fit like a glove and provide a crystal clear view of our lake. This is the real deal, it's an affordable, well built, product. The windowinserts transformed our sunroom into a cozy, year round, favorite room, in less than one hour. Incredible product, great service team, highly recommend this product.
Thank you.
