They don't look like the picture at all. The picture shows a cross structure on the folding backs, suggesting that they are made of heavy, quality metal - the real links don't even have that structure and are made of light, cheap material. The image shows the depth to the sensors, which could be a glass front with a sensor inside. The IST links have a poorly printed image of sensors taped to the front. For over 30 β¬ that's nonsense. At best, these are links to $6-$10 novelties. Do not be fooled. It's safe to say they will come back due to false advertising.
