Bought these last month and had some trouble with my prescription that was my fault on my end, the customer service was soooo great. they replied to my concerns so quickly and we solved the issue immediately, the logistics service was even great as well and the time they use to make the glasses are so quick as well, not like firmoo or eyebuydirect that take almost a month just to get the prescription in the glasses. you can very much tell they care about their customers and the quality of their products, will be ordering more pairs from them in the future! thank you so much sllac
