The spare battery for longer outings a great thing. The shipment was very quick and the shell was also well packaged. The sleeve fits and makes the iPhone 6 not particularly larger / wider. This way I can even continue to keep it in the jeans pocket. The iPhone is obviously little more difficult, is my feeling still comfortably in the hand. The shell is high-quality and looks in golden look very classy. The recesses and knobs for camera are made up and that the operation is not impaired. All in all a super spare battery that looks good and does not interfere with and at a fair price.
