I like the size of this battery.  It is easily pocket-able and feels sturdy enough to withstand the occasional drop.  The flashlight is a nice touch but it would be nice to see a dedicated switch for the flashlight.  The surface of the battery is very close to a matte black finish that helps with not showing fingerprints.  The battery seems to charge my iPhone without any issues.  It's nice that New Trent has included a charging cable with the device so you can just use your iPhone wall charger or PC for charging.
