Once again Amazon did a great job supplying the product. The product does work. I have it on my visior in the car. In my job I am constantly in and out of the car so the ear model blue tooth would get lost. The sound is reasonable, not great, but it works. The unit held its charge for a reasonable amount of time. It was easy to set up and use. I am not overly excited about the product and being a Motorola product I expected more, but bottom line it works, the price was great.
