Thoroughly impressed after weeks of heavy use. 4 high speed out ports, charges with either USB type, sealed on 5 of the 6 sides so water resistant to an extent, and almost a full charge while I sleep. Only thing to keep in mind is the size, it's about the size of 2 galaxy notes ontop of each other with small cases on and about the same weight. Inconvenient if you're carrying it with no purse or pocket space but has no problem fitting in men's jeans back pockets with a galaxy note attached to it and has no problem sitting somewhere while it does its thing.
