Universal Car Window Sunshade (2 Pack)

Really dig this product. Know that in certain light, they do compromise visibility. Go figure, right? Also this mostly flat black material mostly absorbs the heat energy. Sooo, maybe there are gains in a change in color or reflectivity. Perhaps the inside of the window shade/sock be of a lighter color to redirect that energy to the black outside heat-sink sock material?

I bought a set of these last year and LOVED them. I tell everyone how great they are. Not only do they provide privacy and shield from the sun but they keep the overall temperature of the car much cooler. They also keep seatbelt buckles from reaching a scalding temperature.

The only downside to these is you have to be gentle putting them on your car, I know, what a terrible predicament, ha! Other wise they work great. I got them so my dogs wouldn't fry in the back seat when going on trips. I usually only need to use one and they shade the car really well on the sunny side. I even use them while driving and have not had any issues with them making much noise or tearing from the wind.

I repurchase these all the time. I'd say that they last eight months to a year. They can last longer if you take them off when going through a car wash. And after some time, the sun does fade the side that's on the outside. I will continue to buy this on up until my baby is 3 years old. It keeps the backseat a little cooler on drives as the sun is not blazing into the back windows.

We gave these a test - 5,500 miles round trip from California to Florida. We drove 80 MPH (Texas Speed Limit), it rained a few times and was bright and sunny with 120 degree temps other times.

Pros: There is a noticable difference for the kids in the backseat. It was cooler and it blocked the glare so they could rest, and watch DVD's to pass the time.

Cons: kids couldn't see outside very well when there was something to look at.
