I'm on my third, however I have legitimate reason to do so.

The first had the home key area coming up so far you could put your finger nail under it. It was getting caught on my pocket and pretty much everything, it was returned to Best Buy within the initial 30 days.

Second TP - hardware keyboard totally stopped working.

Third TP (current) - I dropped it a few days ago on to concrete... it got a couple small dings and the screen protector took a beating... as well as the home key area again because it's raised pretty far. I'm still going to hang on to this one. The small scratches are just going to happen. If it's only got a few, man up and wait it out.
