It does its job perfectly. Four stars only because the handles of the suction cups are metallic, so if the car is in the sun and you try to remove it carelessly, you end up with a burn

The suction cups do leave marks, but with a little wiping they come off. For Opel Corsa 24 the dimensions require a slightly larger size, if there is a similar product available.

The suction cups do not stick to the windshield and one is crooked, mediocre product, although the store probably sent me a different product from the one shown.

Update 7/08/2024
After 1.5 months of use, the material has dried out and is rubbing off, it has filled the car, the worst, do not buy it

It does the job and generally seems to be of good quality construction but every time I have put it with the suction cups I always find it fallen, so now I just put it on the dashboard. For the price, I would expect it to stay in place with the suction cups.

It is a fairly good product but the material is quite hard, which results in the edges flying off when it is folded and it is not as convenient for storage.

The cut - opening it has for the mirror was insufficient, essentially making its placement impossible.

It comes in 3 sizes, each supposedly tested on a range of models, which are specifically mentioned on the packaging. In my Alfa 156, it doesn't cover the width of the windshield, leaving a large gap on the side, and it could be a little taller.
It is of good quality and the suction cups work exceptionally well...the sunshade doesn't hang/fall, in fact, it's a bit difficult to remove them.
In my car, the slightly larger one would fit better, but I don't know if the same measurement error applies to every car.

I do not know in which cars the measurements were made, but having two different sizes, in four cars that I tried, none of them fit perfectly. If you exclude this, then they are very good in terms of quality. Now, I still do not know about durability. Also, avoid pulling the suction cups, it is better to detach them by hand, it is easier and prevents the back surface from tearing.

For Suzuki Swift, it is the small one, the M is for MERCEDES C200

It is perfect in terms of quality. It should have been a bit bigger though in my opinion (fiat 500). It is good to have measured the dimensions of your windshield before purchasing it. It does not fully cover and leaves some gaps on the right and left.

I bought it for Corsa E. It fits "like a glove".

UPDATE 2024: If you take care of it and fold it carefully, it holds up just fine.

It is no different from the smaller one, for which I have a review here: https://www.skroutz.gr/s/19416139/Lampa-%CE%97%CE%BB%CE%B9%CE%BF%CF%80%CF%81%CE%BF%CF%83%CF%84%CE%B1%CF%83%CE%AF%CE%B1-%CE%A0%CE%B1%CF%81%CE%BC%CF%80%CF%81%CE%AF%CE%B6-%CE%91%CF%85%CF%84%CE%BF%CE%BA%CE%B9%CE%BD%CE%AE%CF%84%CE%BF%CF%85-%CE%95%CF%83%CF%89%CF%84%CE%B5%CF%81%CE%B9%CE%BA%CE%AE-110x60%CE%B5%CE%BA-66845.html

Well, for sun protection, it's a bit pricey but worth its money!! It is made of hard material and you don't feel like it can tear if you pull the suction cups abruptly. Because of this, when you get it, you will have to fold all the creases otherwise you will have an accordion instead of sun protection. Additionally, the suction cups are larger than what we see and they are flat, which means they have a large surface area on the window and they don't have the curvature of the "bad" ones to detach themselves until we get out of the car.
Only substantial negative? The actual dimensions are 108X58 cm.
10/10 would buy again.

Quite a good sun protection and overall it fits perfectly on the KIA Ceed. The problem is that after one month of use, on one side the suction cup was so strong that in the attempt to remove it, it tore and the sun protection (on that side) ripped as well.

The dimensions with the car's glass are incorrect. Normally, the size medium should have been for a large size

During the two-month period, the investment it has in the external stitching started to deteriorate and leave pieces and dust inside the car cabin, which float with the slightest movement or stick to the fabrics. I had the exact same experience with the previous one that I had paid only 3 euros for, but at least that one lasted 2-3 summers.

By far the best one out there.. it doesn't break easily from heat or accidental stepping on it, it stands just fine. I hope they don't increase the price because we speak highly of it. Also, the durability is exceptional, after four years I will change it this year. Okay, the suction cups come off occasionally like in other ones, so better support and with the shades. As for the suction cup that some mention, okay we don't pull it like that.. we remove it with a nail because it is indeed of good quality.

It fit very well in Audi a3 2017, the material quality seems good.

BUT: during the first week, it tore at the point where the suction cup is, I don't know if it's my fault (I pulled it with force by accident) or the product, so be careful when removing it.
