Works great for selecting songs and volume on my phone while im driving i ordered one of these and have a love hate relationship lolgot it for my motorcycle to control my cell phone for music fits great on my handle bar and its safer for me as a riderthe down side is the unit goes in and out and sucks the battery life down fast and when you replace the battery it works even less lolworks good and does what you want but doesnt take long to go wrong does not pair with iphone 5s this thing is quite expensive
