Just want to let those who don't have a communicator know that although an older generation, this Sena is very good. I just got back from a week's tour and 3 of us had SMH10s (1 had a new model Sena) and they linked together well. It made for a safer trip, being able to talk about turns in advance and warn of a spotted deer. It was especially helpful during the 150 miles of hard rain we rode together. I don't talk on the phone while riding, but I have used the SMH10 to stream music from my phone. We have yet to spend a day where the battery in the unit gave up before we did. All in all... rock solid performance. My wife and I both have these and use them to communicate while riding. If I needed one... I'd be talking to "WindTherapist."
