I can only agree with the other reviews: First, I shrugged because of the price, but after the bracket once in use, I am happy with the purchase. Mounted in an instant. By the O-rings also just as quickly attached to another wheel. Not only keeps on the wishbone, but also on the stem - unlike many other holders - and there are other accessories for other useful applications. The shell itself is designed so that they can almost always be to protect the iPhone (slim and unobtrusive).
