I bought this from Costco a few weeks ago and it comes with the adapter to charge the speakerphone at home.  Paired with my iPhone no problem.  On the streets, I can hear callers no problem and they say I sound great.  On the highway, it is a little more difficult to hear and just depends on how quiet your cabin is.  I like the overall look of the device and the I haven't had to charge mine yet.  I'm very happy with my purchase.
