The effect when putting them on is really something else, people are amazed when they see it. They are comfortable, I had them over 6 hours and zero problems and I do not usually wear glasses or contact lenses. I bought them for cheap, for very occasional use. They have surprised me pleasantly, they are comfortable, and the best thing is that they are reusable without problems if they are preserved in saline solution. The relation quality price is excellent and I recommend them without hesitation. My only issue was that the transit time took a little bit too long.
