Jagged edges that feel like sandpaper as I thread them through my pant loops.  There is no way I am getting to my money without taking half the belt out of the loops, so this is more like backup in case I get mugged, definitely not an active wallet.  And like many others said the buckle and arm thing feel flimsy.  Mine hasn't broken off yet as I am beign super careful after reading all these reviews.  But this thing is not built to last.
