The Car Sun Shade for Side Window - Car Sunshade Protector - Protect your kids and pets in the back seat from sun glare and heat. Blocks over 97% of harmful UV Rays - Easy to Install - NO suction cups needed LIFETIME WARRANTY is different than any of the others I have seen.  The ones I have had in the past have had suction cups.  This one doesn't.  There is like a rubbery plastic side that sticks to the window. It is kind of like the window clings they sell at Christmas time to decorate your windows.  You just put it on the window and it sticks.
I like that it folds up nicely into a little package.  I did not have any trouble folding it up but I have used things that fold up like that in the past.
This doesn't cover the whole window but it does a good job of blocking the sun if you place it correctly.  In the back of my minivan there are not shades for the windows.  The windows are slightly tinted but I wanted something to really filter the direct sun.  This works well for that.
I would say that if you need something to put on the window to block where the sun is I would recommend this.
I received this product for free in exchange for an honest and unbiased review.
