The same as giving lifetime warranty which tells you they stand by their product.
But with all that said, even the best screen protector is not bullet proofed. You might be happy with yours now, but what if down the road you will get a new case with a bezel/lip that will lift the edge of sp to the point where you have to replace it? Or you scratch yours? I had my phone in outer pocket of my jacket yesterday, and when pulling out ended up dragging a screen against zipper. Thank God for screen protector! All I can see now is a few hairline thin barely noticeable scratches (only under an angle and with display off). I'm not that anal to replace my screen protector now, but if I end up accumulating more of these - I can always count on multi-pack of my iSmooth!!!
