We ordered a total of 4 pairs of glasses from KZFOO...1 prescription, 1 reader, 1 prescription sunglasses, 1 non prescription sunglasses. The first order we put priority shipping on and they came in one week. The sunglasses we did standard shipping, and they came five days before expected. KZFOO's process is fast, simple, and we have found their products to be quality! I would recommend KZFOO to anyone!
