Unfortunately, the first glasses shattered arrived. The plastic lenses were fine, but it is in the middle, was exactly at the thinnest point, broken.
It was delivered in a really reasonably stable case. Here I must also praise the service since it was converted without difficulty. A photo of the broken glasses handed.
The second was delivered but was then completely fine. It also makes a pretty solid impression. And I also believe absolutely that the glasses are shatterproof. Only the frame ... because I still doubt. I do not want it but also challenging.
The glasses sits well on the nose, it is convenient and the ambient light is also well reduced. The polarizing filters are super. They are perfectly set perpendicular to the plane of polarization of the reflected light from the street.
The glasses are a top recommendation for the price. Only the stability is a bit questionable, especially as it is advertised as unbreakable.
