The motorola bluetooh 500 is very lightweight and sleek but the main feature I purchased it for is the one feature I am very disappointed about. Being able to go wireless. My customers complain that while talking to me they get an echo on their side of the phone, both cell phones and land line phones. It gets so annoying to them that they ask me to cut the bluetooth off. Customer service from motorola is very personable but I still have a problem with the bluetooth. Heading back to the store where I purchased this item for their tech support or hopefully exchange.
