From the description and the HIGH reviews, it seemed like a great product. However in this case, the LOW reviews seem to be the most correct.My problem with the unit was the person who I was talking to ALWAYS heard an echo. Even after repeated attempts to try and wait out a conversation for 15 minutes or more to see if voice cancellation would kick in, was unsuccessful.I did contact support and a few days after not hearing from them I went ahead and packed up the device and dropped it in the mail the day support wrote me back.Support said my phone was the problem and not the device. They also said they had numerous reports about my samsung phone not being supported. However, my motorla blue tooth phone did not work and better with the device. They also said it may have been due to excessive road noise from my vehicle.I drive a 2002 Lincoln LS and a 2005 Ford F-150 XLT. Both VERY Quiet vehicles.The echo even happened when sitting in the driveway with the car off.
