According to the Amazon pics (via the linked site.....)...this unit DOES offer full edge protection.....
Now.....whether it's ALL GLASS, edge-to-edge......or just glass over the screen area.....maybe an e-mail to Screen-Mate....????!
Either way, though......it DOES look nice.....and $25 isn't an unreasonable price!!!
One problem many of us have had with the full screen edge to edge protectors on earlier iPhone versions is that it interferes with some cases where the case wants to get under the screen protector. I am sort of liking the variety now emerging; some full screen and some full screen to included rounded edge.
