I've had this for about a month now. I like it more every day. Mostly, I use it in the car, commuting. Its extremely simple to operate. It holds a charge to last several days (don't know how many). Its volume control is loud enough even for me (I'm a little hard of hearing when there is background noise).But best of all, its the first bluetooth headset I've had (Motorola :{, and Plantronics :| previously--returned) that my customers can truly hear me just fine. I've used it at the luggage carrousel in a busy airport. I've used it standing outside in the wind on a busy street corner. I've used it in my car with the windows open. I've used it in stores. It works every time--without much (if any) background noise going through my calls.It took me the first two weeks before I realized I didn't have to do ANYTHING on my Motorola Razr phone each time I wanted to use my headset. All I do is turn on the headset and go. Its very practical and its more comfortable than I thought it would be once I got a little used to it.Its not all that sexy looking, but it truly works. Guess I'm getting too demanding to settle for just plain sexy.
