Haha... yea I don't quite see the logic in them. The InvisibleSHIELD ones suck the worst... their idea of "full protection" is 10 different small pieces that you have to apply around the phone which makes it look like frankenstein. The Protech one has only 1 piece for the whole front, which is better, but the back is still in pieces (I guess it has to be).
Anyway... they're both around $20 for a full body film, but you can just buy a whole new OEM faceplate for around that price as well.
