For me it did not really hold a Xperia Z1. Maybe I was just hired (?), Or it's really a bit too heavy, which is indeed confirmed in one of the other reviews. But I did not want to rely on the suckers anyway but had from the very beginning before, use it for a "Mod". For all those interested will also equal a suitable guide: For that you take a simple car mount or bicycle holder, ideally one without ball joint or only clip. Depending on your smartphone dimensions also a bit longer available Nokia CR-122 holder is very suitable as a universal. Now just have the suckers removed (double-sided adhesive, easily removable) and glue the car mount on the Speedlink clip. For example, I can recommend Sugru. Might sound adventurous, but creates unique, for I could already reaping many curious glances and enthusiastic :) By the way: although certainly not intended, the holder also holds for the cheap compatible PS3 Bluetooth Controller (in different colors meant it with the colored shaft with curved V-shape at the center). There, the holder will keep very reliable, the holding lug can be in the housing gap of the controller into place.
