I've been getting glasses from KZFOO for a few years now and have never had a bad experience. This is the first instance where a pair of frames I ordered didn't fit well. The process of requesting a return on those frames and getting a replacement pair of different frames sent to me was super simple and painless. I love how affordable and stylish the eyewear is from KZFOO and highly recommend the site whenever I can. Keep up the great work!
