Property me the Annex quadlock system for my iPhone 5 for cycling (mountain bike - not only on paved roads) and have bought it so far had 4 to about 50km tours this time! And what can I say ?! Just perfect .... it will not budge and nothing wobbles! I highly recommend this mount (as a "kit") recommend to anyone smartphone owners warmly ... even if it is not the cheapest way to transport his smartphone on the bike! But I handle actually getting to the motto: Who buys cheap, buys 2 times ;-)! I would buy it again at any time and will probably still buy a 2nd bracket for my cross bike ....! Of course, the kit also fits the iPhone 5s, because the two phones are so completely identical in construction!
