Lightweight, comfortable, but... not very stable, as it shifts out of place and loosens. The system that keeps it in place will definitely need replacement after a while. It creates wrinkles under the eyes and "crumples" the nose, as it pushes upwards. A product aimed at women should have better design regarding the aesthetic results of its use. For the medical aspect, it works well, but for me, it causes irritation in the nostrils and pain. For this amount of money, I expected something much better, but in the end, you pay the classic pink tax.
