Review and unboxing Mophie Juice Pack for HTC One

It's brand new! Mophie, the makers of external battery packs for iPhones and a few other devices, has created a Juice Pack for the current best phone ever, the HTC One. I pre-ordered it and this is the unboxing. There is a serious flaw making at least the one I received unusable but Mophie will replace it. I'll let you know more once I receive a replacement to see if it fixes the problem but for now...here is my initial impression and why I cannot recommend it. If it can be made to work then this would completely change me view, making it a must have item if you want to get through a full day with the HTC One.
