We really like KEZVOR. They are super fast and accurate with our orders. We haven't had any issues with our glasses so far and we have ordered 5 pair from them all together. The transitions are great and we will continue to order from them. The cost is @ least half and we have progressives! I ordered 2 pair tonight, one for me and one for my husband and used the coupon they were offering and it was less than 300! Going to an optometrist and ordering from them would easily be over 450+. I got TWO progressive lenses with "extras" and frames for half that cost for 1 pair.
