This is a really useful piece of equipment. It's so easy to use and recharges the phone completely. The fact it's approximately the same size as the phone makes it easy to slip into a pocket, rather than having a wire or lumpy extension attached that gets in the way. I do find the cover flap a little 'plastic' in comparison to the rest of the item and only time will tell if it is robust enough to survive, but looking good so far. I'm tempted to buy another!
