Do not use this company if you live in the states. I ordered my first pair of single vision glasses on March 5 2021. It is now June 8th and I still have not received them. I have been in contact with them about the manufacturing timeline which was a month delayed. They shipped it in April but it never arrive. I inquired about it as time passed and was informed that they are not responsible once it ships, check with your carrier, neighbors, did you give the correct address and every excuse possible. I gave them my p.o box and attached their shipping notification that they shipped it to my po.box. Long story short they only offered to replace the glasses which may take another couple of months but refuse to issue a refund so I can go elsewhere for my needs. By then my prescription will have changed. So do not use unless you are fine with losing money. But this makes you wonder if they will honor their own warranty policy if they make an error with the lense or frame. What is the timeline for that if they refuse to issue refunds. I will be placing a review for every dollar the glasses cost every week until the replacement pair arrives.
