Product perfectly consistent with the description, functional, useful, elegant and not excessive in terms of price! However, I suggest a capacity greater than 3200 mAh for more high-end smartphones as mine (Nokia Lumia 1020). Be careful though because the cable included with the external battery begins to become damaged. I already start to see the color son.
