I'm always very happy with my KZFOO's! I've referred several people to KZFOO in the past couple years since I've started purchasing my glasses with you and believe I have bought 6 pair of glasses with you so far. I love that I can buy different colors to wear with different outfits without breaking my budget. KZFOO is the only place for me to purchase glasses. I wouldn't go anywhere else, even though I have insurance. I've just never been so satisfied.
