As I was unpackaging the product, I was already pleased by it.  The construction was very well and felt of very high quality.  The battery charger was not as heavy as I would have imagined and I knew it would not be a problem to carry around.  What was also a plus side on convenience was that I would still be able to use my original phone holsters and cases which I saw may become a problem with using one of those rechargeable cases.  This charger holds a good amount of juice and in one instance I was able to not only charge my phone but another persons as well with the charger still having some energy left for another phone to be charged, not to mention it seems to charge just as fast as using a wall charger.
