I just received my third pair of sunglasses by TBD. All three are the Welt Eco Design, just with different colour for frame and glasses. The reason I continued buying after the first one (honey/blue) was, that I got a lot of compliments (well not me, the glasses), then I ordered the black/red ones - gorgeous, and ideal for winter - enhances contrast in icy conditions. I had problems with the delivery service, but customer care of TBD was very nice and sympathetic. Therefore - well, also and foremost because of the quality - I ordered my third pair: green/grey. Clearly for the upcoming sunny days. Highly recommended! :-)
