Sorry, but that's scrap

So I searched around a bit at Amazon and came across this sunscreen of Reer.
First of all, I was very pleasantly surprised because of the price. 3 euros for a set of 2 are almost nothing :-)

Then I looked at the reviews. Many negative items bez. malfunctioning suckers or nonexistent sun protection. Others praised the sunscreen with 5 stars. Hmm ....
My better half I thought should not even be as accurate, finally "has indeed everyone in the car" and all can not be wrong yes !! Or is it?
Well, I've got it so ordered, 2 days later, they were there. Flight unpacked everything intact and in order. We have just tried to attach the car to the windows and they were outstanding ease and reliability. So sucker problems I could not tell.

Then we made our first trip crumbs. As long as the sun is not there, they were to use as a screen completely. Once the sun came out but it was over.
For the one it offers as a sunscreen, you could already go out almost by deceit. Those things are what the pure sunscreen terms "scrap" (sorry for the hard expression). Since we have a seamstress in the family, we were lucky that this has sewn us a dark cloth over the real sun protection.
But let's be honest ... I do not buy anything for it later manually even having to stitch up. This lot is a penny worth assuming that with which the product is declared - sunscreen.

On Amazon: Since you too must make you even noticeable when such a deficient and defective product will be offered. The description must be different because something dangled here is what satisfies the product in any way.

From me here expressly not advise !!
