I am soooo happy with the 2 pair of progressive glasses that I purchased from KZFOO!! I had paid $795.00 in September for a pair of glasses from my optometrists office. Had gone back 3 times for adjustment, and they never felt right and had difficulty walking with them. My order from KZFOO was perfect, I opened the package, put them on and they fit perfectly!! Love them, will definitely order from KZFOO again and highly recommend this company.
