Caution to all 4S owner!

I got myself less than two weeks before an iPhone 4S as the successor device. As I discovered when the 3GS that the battery does not hold long and I'm often on the road I was about to set a car charger to me. I found that mumbi Car charger solid and the reviews were good. The only skepticism I had was the fact that hardly any iPhone 4S was present review. This skepticism has unfortunately confirmed:

As I drove to work, I closed my 4S to the charger. The red light confirmed the current flow and everything seemed normal. The iPhone 4S confirmed again and again the current flow. On / off of the store. The whole was beaten two minutes back and forth and then threw over. To my horror, I realized that it was probably a short circuit and the sound unit of the iPhone has gone away. I was forced to send the phone in the same service. I must also stress that the cell phone has never fallen out of my hand, or otherwise.

This is clear to me that this device is not combatible with a 4S and the plug also a tad too big fail why the introduction or the unplugging things turn out as a bit of a challenge. In addition, I must agree with the previous reviews: The charger does not look like the picture. The labeled side "mumbi" on the plug is black like the other side.
