I love KZFOO, the price, the quality, the styles, and the customer service. I ordered the wrong perscription the first time (used contact rx, not glasses) and it was easy to return them with a credit and reorder them with the right rx. I love the glasses so much and I've gotten lots of compliments. I have a very strong perscription but the high index are so much more reasonably priced through KZFOO and I don't look like I'm looking through a glass bottle. Thank you for helping me look cool for cheaper, KZFOO! ❤
