Experience With Sena and their 10R
This is not intended to be vendor-bashing. I know a lot of people like Sena, including the 10 model. I just wanted to share my experience, which I have extensive documentation on, as a data point for others.
Got the 10R in early May '17. It didn't come with good installation instructions and the ones on the Sena site were also poor. It was a major hassle to install in my Shoei GT Air and even then, it didn't fit well. Then, the speakers were not loud or clear enough to be heard well at highway speeds inside that helmet, which is supposedly a "low noise" helmet. I had to buy the earbud adaptor and use buds. I found the three-button control system to be complicated. Also, it did not differentiate well between "taps" and "presses" which are different commands. Furthermore, any interruption of the bluetooth signal from my phone caused it to lose the bluetooth connectivity. So if I was listening to music and got a phone call, the system will not come back online after I hung up the call like a regular bluetooth headset would.
Then, in late Sept. one side quit working. I contacted Sena customer service and found them to be very difficult to deal with and I found their policies to be very bureaucratic, not in line with other vendors I deal with. Instead of just sending me a new control unit, they made me rip everything out of the helmet and send it to them, which I did. Then they lost it and wouldn't send me a replacement until they found it. Then they said they were moving their warehouse and I would have to wait for that to get sorted out. Then, last week they said 10Rs were out of stock and they had no idea when they could get me one. I asked if I could get a different model instead and they said no.
But today, I sent them an email asking to speak to someone in Sena management, not just customer service. Within three hours, I got a notification that my replacement 10R was on its way. You draw your own conclusions.
