User of the iPhone and biker I was looking for a nice kit to listen to music and be informed of incoming calls. Purchase iBike Rider the positives: Easy Installation Quality music its proper the price Cons: A week of use = the atria are too big, and prevent the same glasses wearing very thin branches Incoming calls are still detected, but not after a few days of landing = the switch no longer works ... The scratch peel off ... Disappointed. He returned in its box.
