Has anyone tried this yet?. Does it add any kind of bulk to the body by adding a whole glass front? How hard is it to get of as well? I contacted spigen about how disappointed I was with the curved crystal screen protectors being so easy to indent and scratch and they responded by suggesting I try the GLAS model as the hardest at a rating of 8. It's $34, which seems pretty hefty, but I am willing to consider if it is really good.
