I ordered a glass one. Not a plastic. The seller posted images about how it fits with even these covers. Just waiting for it to arrive.They may be, but the Body Glove screen protectors aren't.
What I would like is a protector that covers all the glass on the front of the screen, and not just to the edges.
That way there is nothing that could inadvertently catch or lift when in a case.
