The products are good. However, the complete support is extremely disappointing. I ordered 3 pairs of glasses, they arrived after 5 weeks of delivery (I had to ask several times for them to be sent at all). Of these, 2 glasses were unfortunately too small for me, so I decided to send them back at my own expense. You then have to send them back to Spain at your own expense, which costs about 15 euros by DHL. After 3 weeks still no answer came, I wrote several times to the customer support. After the 3rd mail came the answer that the glasses arrived damaged and therefore no refund could be made. Without proof photos, without sending the glasses back to me. The glasses were simply retained, so that I am now stuck with the 40 euros costs plus 15 euros shipping. What is still to be noted that the support answered me partly in Spanish, not even in English. I will never order from this company again and also advise anyone not to do so.
