Just got this from Costco. One thing from the Amazon.com reviews and descriptions was that it's supposed to only come with a car charger. But the Costco bundle comes with a AC adaptor where you can plug the car charger into. That was great, I wasn't expecting that.
It was very easy to pair the bluetooth with my iphone. And while it's not as loud as my car stereo, it's loud enough to work perfectly well. Sound quality is fine too.
One thing I did was remove the wire-clip in the back (pinch inward to remove). I'm using velcro to attach it to the hidden side of my car visor, sideways on the vanity mirror cover. It's thin enough that when the visor is up, I can hardly tell the Jabra is in hidden in there. And just flip my visor when it's needed.
Operations are simple. There are a couple of buttons on the side, one for volume up, one for down. The upper body is the main button: press and hold a few seconds to turn on, same to turn off. One quick press to receive a call (of course no need to do the "slide to answer" thing on the iphone), same to quit the call. And finally a longer press to send the call direct to voicemail.
There are indicator lights for on, bluetooth (paired/searching), call in progress, and low battery.
Highly recommended for people who want just a simple hands-free solution.
