So I'm very happy with the product, the spectacle served its purpose. My daughter is 8 months and had no problems after a short familiarization with the glasses. I can not understand the negative reviews, so if you are not extremely tighten the belt also arise definitely no pressure points! We never had the Problem.Über the cap there was no slipping, no hat we have not tried the glasses. With the Velcro it is easy to put on and easy to adjust. The grease spots from the sun cream could be easily removed from the glasses. So there is nothing negative about the product.
