Back Window Sun Shade for Car,1Pack 39.4"x19.7" Car Window Shade for Baby,Rear Window Shades Protect Child, Pets from Sun Glare and UV Rayse

On the positive side, the suctions that came with the screens are top quality. No problems keeping them on the windows even in the Arizona sun of early summer. As the description shows, there is some flexibility with how it's placed as it is a fabric screen, therefore, soft and movable. Also on the positive side, I felt comfortable driving with it in place on the side driver's window as it did not impair visibility from inside the car. However, the negative was that it did not block as much light as I'd hoped it would. I have a meter I use to measure the sunlight for houseplants, and I don't know what units the device measures. Full sun in June in Phoenix mid day had a 2200 rating. Behiind this windowscreen it was 1600. Full shade was 300. So bottom line, if you are looking for a car window screen that is easy to see thru while driving which is able to shift to the dimensions of the window, sticks on window well, and isn't needed to block a whole lot of light, this is the perfect product. If you need more sunlight blockage, I'd look for a silver coated material instead. For Phoenix summers, I will need more.

Back window shade - nope, way too big. It’s frustrating how the pictures with this sizing show side windows when it’s not that big. It’s also frustrating that the reviews listed were for a different size so I thought oh it’ll work. When it didn’t fit my back passenger window I looked at the description more closely. Yes the sizing is listed but who knows off the top of their head how many inches a window is? So I tried it on the rear window on the back hatch. Still too big. If I would’ve only saw pictures of rear windows instead of side windows, I wouldn’t have gotten it.

I, for some reason, thought this was for the side window, not back window. It’s ok. It reduces the light coming in.

This is a must have for those hot summer days. I like how it stretches to fit many different size windows. The suction cups are strong and it blocks the sun well.

Disappointing: Keeping the 2 recent small boxes in the front seat, just in case or a return. This box went missing ???? Cannot return!! Gave this to a friend, still would not work for her car Moon Roof either. Very disappointing!Colorado Sun IS HOT, we are closer to the sun by 5280+, I expected as the photos, the elastic to stretch and the suction cups to hold, even soaking for 30 seconds. PLUS cover the back window of my Scion, none truly worked.Our cars must be protected, and what I found was most rear windows run SHORT by 2-3 inches, as this netting has.Be careful when ordering. Came within the time allotted and netting seems durable, but not the stretched, be aware of this

Having tested out a number of car sun shades, I've realized that none of them are perfect. The electrostatic vinyl mesh ones lose their stickiness if you move it around a few times. Clip-on roller blinds can damage the inner window seals. The mesh shades that you pull over the top of the doors can impair visibility, especially in the rain. My favorite sun shades are still the tinted vinyl ones that adhere to the window like a phone screen protector, but they are difficult to cut to size and install without bubbles and you need to get the bottom edge under the window seal in order to be able to open and close the window properly.These suction cup shades are my second favorite. Suction cups in 4 corners make it especially secure, and the borders are just elastic so it can stretch to different shapes. My only complaint with these is more aesthetic---the inner mesh is not very taut and sags, even when the border is stretched out. Otherwise, they are convenient and easy to install, and do a decent job of blocking the sun without impairing visibility.

They don't cover the whole window on my Volkswagen Jetta, but I guess any blockage is good. No children are involved, whereas in Florida, the sun gets the interior of your car so hot you have to open the doors and let the A/C cool the car down before you can go anywhere. The screens were easy enough to install. Please note that when these are stuck to your windows, they cannot be rolled down. Not a significant issue where I live, but farther North. Again, where I live, it doesn't help much with the heat. These screens definitely block out whatever you may have in the backseat, so that is an added benefit.

Came with the mounting suction cups, instructions were easy to follow. Proper sizing and stretched for the maximum coverage! Great for the sliding door in the van we have where our youngest is rear-facing still. Would recommend!
