I have got my free PB, it's amazing.
after days using, I find that , when i hold the PB by hands, especially the left of back cover , there is a sense of "empty";
according this picture . that is , there is a gap between the battery and back cover . because the back of PB is soft cover , So it is more obvious when you touch the back with some strength .
