What do you think the material is? TPU? Bummer that you didn't like it ... I hope people don't hold it against me if they don't like theirs

but mine doesn't bubble up around the buttons. The only place the fit isn't perfect is at the bottom where it's sorta flimsy. I just tried the fix that someone did with the iSkin cases a while back with a hair dryer and freezer... we'll see if it works.
