It has been tested for a year with quite reliable protection, and this year a second one was purchased for a different vehicle.

For Renault Clio I had to get the smaller size. For Nissan Qashqai it is just right. It does a very good job. It keeps the temperature relatively low even if you leave it in the sun for a long time

Pay attention to the installation instructions. The packaging says that the logo should face outward, but the reflective (silver) side is the one that should face the windshield/sun for better heat reflection.

I use it this way in a car with nano-ceramic tint on the windshield without any problem.

Why then do the instructions say the opposite?
1. Wrong translation or printing in the instructions. This happens quite often with general-purpose products.
2. The instructions were written for another model from the company and the same ones were used.

Try it by placing a thermometer inside the car.

Excellent sun protection with a deep opening at the top that fits many modern cars. It has one downside. Because it is made of that material that resembles aluminum foil, it accumulates incredible heat, so in a heatwave you need fireproof gloves to fold it up!

Very nice sunshade, especially for the money...
It loses 1 star because when it gets hot it loses a bit of its shape, and when you fold it you struggle to get the clasp right so it stays closed, but otherwise perfect.
Note: Because I saw some comments like it fades or leaves residue from the print on the glass... The reflective surface (silver) goes on the outside. I know it’s silly to have a nice design and not have it visible, and the manufacturers don’t help with the photos they upload showing the print facing outward, but it’s just simple physics...
Finally, the 140x80 is a little bit wider for a Fiesta MK7. I think the 140x70 is the ideal size.

The packaging says that the logo should be placed facing outward.
However, I put it on upside down with the silver side facing outward. I have contacted the company and am awaiting a response.
On a Primera P-11 144 2001, the 130x70 size fits very well!.
It is made of a hard material and stands very well without sagging on the inside and keeps the heat very well.

**Update**
3 days after purchase and indeed the white color started to fade onto the sunshades.

Perfect!! It doesn't wrinkle, it doesn't shed, and most importantly, it doesn't let heat into the car!!! It fully covers the window, not a single ray of sunlight gets through!

For its price, it does the job at first, but it doesn't seem to withstand strong sunlight.

Positives:
Almost no sunlight/heat passes through.
The 130x70cm size fits very well on the Yaris 2025.
It is quite thick and stable.

Negatives:
After about 4 months, it starts to wear out significantly.
The material/print "bakes" from the sun and leaves a haze on the windshield.
When it gets hot, it sticks to your hands when you remove it.
The picture already shows distortion and "melting" of the surface/ink.

Very large, hard and impractical. Impenetrable by the sun, but sized for a truck. There are better and cheaper options.

Very effective at shading and easy to fold and unfold. The only issue is that it gets very hot and is difficult to pack up after exposure to the sun.

Fits well in an Opel Corsa E (2015-2018) even though the car has a very deep dashboard. The quality of the sunshade is excellent, nothing like the other ones for €5 that after 1 month start to "break" and "sag" from the heat. I'm talking about the 1.40x80.
Update after 1 year I haven't seen any wear on the material.

Very good. I got it in the exact dimensions and it fits perfectly. (I use the driver and passenger mirrors as support so that it doesn't fall.)

I have only had it for a few months, but it has been very convenient for me. It fits from the inside very easily, fits perfectly (KIA Niro), and there is absolutely no problem or wear so far.

It is quite thick and sturdy and seems to do its job well. In width, it covers the entire windshield and only in height does it leave a small part uncovered, but overall it fits well (YARIS). I've had it for about a month and the only drawback is (unless I'm doing something wrong) that to keep it in place, you have to lower the driver and passenger sun visors so it rests on them. Overall, no complaints.

Terrible quality and fake construction!! As soon as it is exposed to high temperatures, which is its natural environment, it starts to fade and deform. Stay away…. There are much cheaper and better quality ones on the market than these!

I confirm what I read in the comments. It really has very good quality and its material is indeed more reinforced. The design is beautiful and covers the whole window well. I have a Smart car.

Sturdy material. No comparison to those you buy at gas stations. Very good protection from the sun. Its durability over time will show. So far, I am very satisfied with the purchase.

It fits quite well in the Mitsubishi Asx 2010. I have had it for 1 month and so far I am quite satisfied. The button it has to seal after wrapping is convenient. Nice print (it was also the main reason I bought it)
