Just got my New Trent IMP52D External battery pack, but already I am impressed after just getting it out of the box. I noticed immediately that it is much more solid, and feels like there is a much bigger battery inside than the cheaper competitors. I like the laser pointer and flashlight, but I think it could be better if there were separate buttons for the lights, because it's annoying having to hold the button for 3 seconds for the flashlight however.
