I was very happy with this product. It was easy to set up, and the quality of the sound is great. I had bought one, for my husband and he liked it so much I bought another for me. I also loved the feature where you speak the name to call. It has made my driving much safer. The earpiece is comfortable and stays on well. The only reason I gave it 4 stars is because there is a little delay when you answer the phone, but not enough to cause any problems with the call. The price of this product if far below the similar products found at the cell phone carriers. Great buy!
