Not the expected Quality and Service
I thought that there have competitive prices and the assure me by chat delivery time is 7-10 days. First the glasses was not even shipped after 7 days. When they finaly arrived in Spain, i got serval requests from UPS for documentation i had to provide so the glasses could pass customs. Finaly i found out that the glasses was shipped as "comercial sampel" so it was treated as medical goods for comercial purpose. To impost such things you need a license in Spain. So it took about 8 days to assure the customs that the glasses are for private use. I had to fill out 2 forms and send 3 confirmation letters. Tenda did not help at all and told only this is unusual. On top of that i had to pay a fee of aprox 25 EUR for the Services of UPS what included a fee of 6 EUR from the customs for the extra processing. As this would not be enough finaly i got the glases i ordered progressive glasses, i have already two pairs and wanted a spare one. First i noticed that the lenses are not well fixed in the frame they look a few millimeters out on top. Then i tried the glases on and they are only useful for far vision, the intermeditate range does not work at all. For the near vison the part of the glasses what is corrected is so small tha i can not even see a full A4 page sharp. So the glasses are total useless. I have put in a reclamation, where they told me they have nothing to do with the customs problem and the small vision is normal. they asked me to send a picture what shows the lenses looking out of the frame. So far no response after two days. It was defently the first and last order, if they are not fixing this problem
