The interchangeable lenses sit precise and taut in the frame. It included a brief guide that describes the change. For the insertion of the glasses but lacking the crucial clue, one must slide easily into the socket the frame spread a little with it. From "mini magnet" by the way no trace, the glasses are attached classic and purely mechanical. However, this is a mistake of Amazon, at Uvex glasses is described correctly.
The glasses will be delivered in a flexible goggle pocket, in the orange and clear glasses find their place. The bag can be secured with an attached plastic carabiner on your belt or harness. Pocket, zip and carabiners are well made and should last. The padded gig bag protects the glasses well, but for the sport use almost a little too bulky. For space-saving storage you should hire to buy a simple cloth bag.
To look and function: Both the black-red and the black-mat look good. The black-red with noble red and gold mirrored lenses in natura sees significantly better than on the product photo. The black-mat has a satin chrome frame held beside white silicone inserts. The black-red looks in my eyes considerably sportier than the black-mat.
The frame is very well located and very comfortable. The glasses are 25g easily. The glasses have no distracting distortion and no color aberration. The mirror glass of the black-red tinted slightly bluish, the tinted glass of the black-mat is dyed neutral. The clear glass shows a slight loss of contrast, however, this is inevitable in this price range, as to avoid only with high-quality (and very expensive) compensation. The glasses are very well shaped and proportioned, and provide perfect protection for the eyes. The spectacle is but to not completely, so that adequate ventilation is provided for movement. If you stay for a steep stand, it can however toned. The fog will disappear immediately when you sit down again on the move.
Overall, the glasses make up here a very good impression. Unfortunately, there are also downsides: two glasses creak quite considerably. With two glasses the strap were very unevenly firmly bolted. Against the creaking there Remedy: Remove the glasses and the frame with silicone spray from the diving and water edit (must not contain solvents). The unequal screwed strap can be corrected with a precision screwdriver. Both are production errors, a silicone coating would certainly not be too costly, and the uneven fitting is eigtl completely avoidable. Both defects are the price of 50 euros in my opinion, does not do justice. Therefore, I prefer it from a star by a total good overall impression.
Apart from these correctable deficiencies I'm very satisfied so far with the glasses, especially the black-red model I find very well done!
