This device isn't even worth it. I mean...come on $26? I rather spend that kind of cash on multiple Nes games and some food rather something that is awkward hence the review says. Also extended battery packs never really lasts as they are cheap Li-ion from third parties. You might as well be better off spending that kind of cash on an extra PSP official battery cheap online. You can simply replace the battery with the other one. Fast, Easy, User Friendly for your Hands.
