The product seems to be pretty simple but you can't use the phone if you don't have your charger connected, that is why I bought it in first place! It charges up great and does exactly it promised. But without a cord there are no calls or texts!! Not very happy about that! Also when using navigation on app like google maps - my GPS constantly drops off. This happened with both the car charging port so now I'm just carrying around an extra one I guess.
