not bulky at all
No, its not been my experience. i put mine in my pocket all the time. its not bulky, it adds more stability in my opinion when holding it in your hand. Its a nice device, the only complaint about it for me is that it doesn't have the mah of the original juice pack. it won't bring the phone back to full charge twice or 1 and a half times like the juice pack will. if i'm not mistaken, the juice pack is roughly 1800 mah and the air is around 1200 if that. i like it though, its not too much bulk for my taste and i'm happy i bought it.
