I am having this for quite some time and I feel like it is of very bad quality product with very bad quality lenses. it is not atall comfortable and spectacles does not fit in it. I dropped in once from my hand it broke into very small pieces. the lenses gets scratches very easily and gets very dirty at times. it does not fit people who have a little chubby face. after using it for sometime I get severe headache. it is not worth the money.
