EDIT: My original review is below, but here is some extra information: After two months of use, this device is still working well, but the silver paint is almost all gone and the case I bought for it is not rigid so the button keeps getting pressed in and the battery drains every day. I need to find a better way to carry it... The paint problem shows a definate lack of quality and if I could change my rating I would reduce this to a 3 star review.I have had this headset for two days now, so this reviewer can't speak of the potential for battery problems or how durable it is. However, so far I am very impressed. The quality is beyond compare, I have carried on several conversations and then said "by the way, I am trying out my new headset, how does it sound?" and the response it always that they didn't know I was using one! I am so happy to have found this because I get nervous driving and dialing, plus I tend to drive fast and I like to have both hands on the wheel. I'll be buying the car kit next, but I still want a headset for use while walking around and while at events or fairs.I have a Motorola V600 and it paired easily, though since this was my first bluetooth device and there is a pairing code to enter I had to read the quick start directions. From the time I opened the manuel to my first call it took 3 minutes.Cons: It didn't come charged, which I get upset about because I am too impatient to wait. Also, when you plug it in it can take up to 5 minutes before registering the plug, which made me think that it was broken at first. Next, it doesn't come with a belt case and it is a strange size so buy the belt case (I am waiting for that to come so look for my review of it later on). And finally, the battery is not removable (I found out that this is typical of these headsets, but I still would have liked to be able to buy several and change them out).Other than that, it is a perfect headset. Since those are minor problems and are typical of other headsets, I rated this model 5 stars.As for me, this is my first bluetooth headset. But I know people who have problems with other headsets and this one outperforms all others that I have seen...
