I have used Sena for years... They have been reliable and worth every penny. I have recently been looking into the SPH10 also since I only wear a helmet when the weather is rain, or cold.
In my helmets I use a Sena20s.
Yes, very reliable and good support for Sena if you do have any questions or problems!!! I like the SPH10 headsets because they fit over your ears and backside of head and not on top of head so you can still wear hats or ball caps and you can pair up to Four headsets for a small group of riders if needed !!!
