Hello. This product fits perfectly my iPhone 5 C. Seems to have been sold so all is consistent. The color of the shell (blue in my case) is identical to the phone, so perfect for the look. Extension and increases the weight but it is not a problem for me: This is an extra battery so be aware of the squeeze somewhere! I would say that it gives a beefier appearance to this mobile I love but is just too thin for my taste. (It takes for everyone!). Attention his vocation is not to protect the device but to increase their autonomy. No incompatibility ignition message. Original power cord (not supplied) connects perfectly. Cord plugged in and turned off shell, then recharge the phone handles the battery automatically. Excellent. The ability to connect another device to the USB jack on the side is clever. On / off nice and toughness suited to avoid the risk of setting off too easily into a pocket. All features of the phone (on / off, volume etc ...) remain fully accessible. Approximately doubles the autonomy of my 5 C. Very pleasantly surprised with this purchase for its value for money I recommend. Amazon Sending very efficient and fast. Thank you and see you soon.
