I just received this as a Christmas gift. As I am not super techy I couldn't believe how easy it was to set up and link to my Motorola Razr.I love that it came with a car charger and an AC charger and didn't force me to buy these seperately.Everyone who talks to me can't believe that I'm on a handsfree device. Now, it should be noted that as I just received this for Christmas and I live in upstate New York and it's freezing...I have yet to try it with the windows down.I also enjoy that I can make calls with voice commands such as "Call Mike Smith work".I wish there was a visual display that would show me caller ID, but I can just leave my phone close enough that I can pick it up.If needed, the switch from the phone to the handsfree is very simple.One side note - I wish the magnet was stronger. The first time I attempted to push the microphone back in it popped right back out, so when I tried again with a little more force it pushed the device off the magnet and dropped onto my nose. It didn't hurt a ton, but I have since learned to use two hands or the combo thumb/middle finger one handed method.
