Cable too short and the connector is too large

In the product description, it is true that the cable is pulled 100cm long, but when you actually pulls the cable to one meter, is much train on the power that he get out fast heartbeat. To produce effective length of the cable without too much tension is about 25 to 30cm. Since the removal of my cigarette lighter of the phone holder on the windshield is approximately 70cm, I have no chance to install the connector, without being pulled out immediately.
If the iPhone is in a plastic bag, the plug does not fit, because it is too wide. So you have to remove the phone only from the package before you can connect it to this cable. But who does that?
For me, this cable is unusable. Due to the low price is not worth a return. Pity for money!
