As far as indentations? Yes, I can attest to the accuracy of her statement. If you use your nail, you're going to put a permanent mark/indentation on the protector. I would imagine using a stylus would be a bad idea. As far as the bubbling she experienced with a fresh install, I think she rushed it a bit. Even though she eventually got the bubbles out, I didn't have that problem. I essentially had a large bubble in the middle that I easily worked out. Install is incredibly easy. She did say something about the adhesive separating and a bubble forming associated with the indentation. I have not seen that. I think that may be because she used her nail on a fresh install. I'm very gentle with my protectors for the first 48 hours. I've only got a couple indentations and they're clearly where I used my nail. Otherwise I clip my nails, so it's not an issue. Everything else she had to say about it are true: fit, clarity, etc.
