Amazing company. Our family of 3 has ordered at least 15 glasses since we started using KZFOO. They deliver to us in 6 to 8 days using cheapest service. Rx has always checked out at doctor's followup. On occasion where we didn't like fit or style return was pretty simple and 14 day no question policy works. Don't know about designer lines only buy their line so far. Great price and coupons.
