Works as described - only good for a car w/o an aux port. Connects to phone by Bluetooth. Call quality is okay. Audio quality is okay, not great but as expected for an FM modulator.
One major con, it can be tough to switch between devices. On a recent road trip, we had it connected to an iPod touch then we tried to switch to mother device and it would only connect to the touch...eventually had to pull over, get the touch out of the trunk, and turn off its Bluetooth in order to sync to another device. Not very user friendly especially while driving.
It does usually stay decent enough for me to keep it n one station for my entire commute. The charger is also just okay - don't expect a fast charge.
All that being said, it makes my commute in my beater easier and I would buy another if it died.
