“Overall it has a good quality/price ratio, and the sunglass does the job quite well. There is only one downside in the design probably not much thought behind, and that is when it comes to changing the lenses. Removing/mounting the lenses is hardcore, you might end up breaking or scratching the lenses, I found a non-siroko-owned youtube video explaining how to do it and after more than half an hour of attempt managed to do it. probably one is expected to buy sunglasses for each lense which then selling lenses makes no sense so does not the price tag either”
