Poor quality products

I purchased sunglasses for my boyfriend this past Christmas. It is now middle March and the sunglasses look horrible. All the reflective coating is coming off. He looks after them, and after only 3months they look like they should be tossed in the ******* bin. I'm very unhappy with the quality of these sunglasses. Even the pair he bought years ago at the pharmacy for a third of the price still look better than these do.
