Love Them

I love the way these are so convenient. Just put them in the console or glove box and store until needed. I bought a multipack to share with my children and husband for our cold winter weather. I would definitely recommend for anyone living in northern states.

Used it for home insulation in Iowa winter

I put these up over all my windows during winter in Iowa, it really brought the heating bill down. I just placed the edges on the wall surrounding window frame itself, and sealed it up with some masking tape- for easy removal later. Cover it with curtains- you'll never notice it! Aluminum can block up to 80% of heat from passing through. So while it doesn't keep cold out, it keeps heat in.

Emergency blankets

I just wanted these for the cars. I have several driving grandkids that I want them to have in their glove compartments. You never know if you might need one of these if your car breaks down in Ohio weather.
