“I ordered a Photochromic model but the glasses I received do not react to sunlight conditions at all. The glasses original state is pretty dark already and it does not change, no matter how dark or dim the environmental light is. My suspicion is that I have received the wrong model.
Which brings me to another minus: there's no Text or label on the box to uniquely identify the product in the box.
The third point of critique is the "DrySky ventilation system". These holes in the glasses redirect airflow to the glasses (which indeed keeps them clear) but they also blow the cold winter-air right into your eyes. This gets super-annoying after 20km or in heavy wind-conditions.
All in all: I'm less than satisfied, even if the product was price-reduced to 35 Euro”
