This little device is perfect for my older model car. My Acura does not have Bluetooth for music just hands free calling. It stays charged for sooooo long! I have only needed to charge it once since purchase. Even if you plug it up and keep it plugged into the charger, it’s so small and sleek that you really don’t notice it. The sound quality is better than my fm radio and so easy to set up! The range is far as well. I will say that would be my only con. The device is still functioning even after you turn off your car so you do need to power off the device before you shut off your car. I have left it on plenty of times and don’t notice it do anything to my battery but it will connect my call to it when I’m on a phone call inside my home. But overall I love love love this little device!
