EcoNour Back Window Sun Shade for Car | Rear Window Shade with 99% Sun Protection from UV and Heat | Sun Shade for Car Window Baby Offers Complete Coverage for Rear Windshield | Medium (39"x19")

I wasn’t excited that the suction cups were not sewn in and they fell off a couple times as I tried to put this in. Then I realized this is a perfect fit into the frame of the rear window of my 2012 Prius without using the suction cups! It seems as if it were made specifically for this car and holds in place very well. Due to the slant of the prius’ rear window I can’t see out of the rear window when it’s in place however, but I planned to use it when needed some ready on longer trips and rarely if ever while actually driving, so it works for me.

I love this product it's working great for me. Blocks the sun during the day and the glare from headlights in rearview mirror at night (I don't have to keep reaching up to flip the switch on mirror) yaaaaaay! Oh yeah, car is cooler on sunny days as well. I would've given a 5 star for suction but a few times before I drove off had to get in the backseat to stick it back to the window, probably just the heat but it only that one side so far (thank goodness). You can't let the window down all the way in the backseat other wise it flaps around but still stay secured on both sides. Great value to me for the price! Will try to to remember to take a video to post later!

I put these on my 1992 190E 2.3 and they fit perfectly and work perfectly. One hang up was that the rear window's heating element is embossed on the inner surface of the glass, and that meant I had to use tiny drops of plastic glue to fix the rear share in place. Some Goo Gone will easily remove the rear shade when I no longer need the shade mounted. The side shades clip onto the top of the side windows which roll up all the way. The suction cup at the bottom of the shade works correctly. A button retracts the shade when not needed. Materials and quality of workmanship are adequate, but I give these five stars because for the right car, meaning a small car, these are perfect. They cool the interior dramatically and result in very strong air conditioning that without these shade did not work well at all. These are inexpensive and they are effective, but the 190E is a small car with a small glass area. Do not expect these to fit as well and work as well on a giant SUV. Those cars require the factory add-on shades, not these. Five stars.

When it sticks, this product keeps the sun out of our car and keeps the car cooler. However, the section stays less than half the time. Needs better suction especially for a product you use in the heat!

TLDR: Is this a very cheap product? Yes. Does it add shade to the rear window? Kind of. Is it practical or safe or well constructed? No. First off, I don't know how this product ever got any 5 star reviews. Here's why: 1) Visibility is dangerously reduced on the rear window even when pulled tought. 2) When tought, the suction cups do not like to adhere even with a clean window & with dry or damp cups. 3) After following directions and properly installing, the product leans forward letting in sun at the top and the only way to circumvent is to try and stuff the top edge into the crease between the rear window and the roof. Even then it will eventually pop out and create a horizontal beam of blinding light piercing your soul and leading you to fear whether you're going to make it to the next offramp to remove this travesty or keep going and gamble with the Grim Reaper. Will be returning. Side note, who's window is oval shaped?

I absolutely love this sun protecter. I brought it because I seen someone looking into the rear of my SUV. Not only does it protect and keep the back of my car cool it keeps prying eyes from seeing what's inside. I can use it while driving and still see out the back whether its day or night. It's easy to install and remove and it's a perfect fit for my vehicle. I use this all year round.

So this sun shade lives up to its promises on: -How much it shades -The suction cups are not separate from the screen, technically -It seems to be well made in terms of sturdiness and materials But it is not actually usable- At least in my 2014 Corolla. The rear window in our car is at about a 45 degree angle. If you have a A SUV, truck or minivan where the window is straight up and down, this may work, idk. - it only has 4 suction cups -The suction cups are positioned very stupidly for a window at an angle. The suction cups are on opposite corners. So you only have good positioning on the left and bottom right (or vice versa). This means the shade hangs off the window by a few inches on one corner and after the shade is in place a while -like while we are in church (2 hours tops) it pulls the top suction cups off the window so it is totally hanging. By the bottom ones. - if the shade would stay tight to the window, visibility through it would be perfect. But since it hangs down off the slanted window, you can’t see through it at all.

I drive a 2018 Sentra and I have this on my back windshield. It is basically the same length of the window. The suction holds and has never fell off. I did notice after like a month or so the middle started drooping in the center but I just moved it up some to place the upper part of the shade into the lip of the window and roof of the car and that actually made it better. It is a little hard to see out during the day and some at night when it is up, but I can still see the silhouette of the cars behind me. Overall great buy for sure.
