This little guy is just amazing. This is my first Bluetooth headset- and the first headset of any kind I've ever regularly used with my phone (I never could stand those corded ones). I bought it primarily for when I'm in the car, but now I find myself using it all the time, and finding out how many wonderful times it comes in handy. Talking to a friend who wanted someone's number, I was able to go through my phone address book while still talking to him. And being able to roam around the house, or use the computer without getting a neck cramp is priceless. As for this specific model- it works very well, and as advertised. Battery life has been just great, as is reception. It's small and light enough that I soon forget I have it on, and can keep it on pretty much all day. My only complaint is that it doesn't fold up all that well to go in a pocket, etc. But I guess if it did, then it probably wouldn't be very comfortable to wear, so I can't really fault it for that. I don't think I will ever have a phone again without one of these guys nearby.
