Nice glasses, but not really suitable for the conditions in a man's pocket, where they had to share space with a wallet. After three months, both yokes were not really connected firmly with the actual glasses. A touchdown was no longer possible. The glasses are extremely light, on the one hand an advantage, on the other hand the spectacle stands out with every grimace of the nose. The successor model, which I then had to get myself, has a metal shell and keeps for 6 months with no outward signs of aging. Still, I give it 4 stars because the conditions in my pocket probably does not meet the standard.
