Unfortunately, they do not deliver what it promises. For faster pace (from 140 km / h), the smartphone vibrates strongly. For an even faster pace my smartphone is not once fallen out of the holder. So, to describe it exactly: the piece of the bracket to which the phone is attached, has fallen from the anchor, to which it is attached.
So who has an older car that does not completely calm situated on the road, I can only advise against this model. In newer cars, the problem may not be as strong. However, there will not be much better in cobbled streets or simply troubled with newer cars.
