I have a very good opinion of these foils and recommend them. I keep the phone in the case and just use the screen protector. I also don't tend to drop it from my hand and don't put it together with things that might affect the screen like keys. So, I only use the foil to protect it from scratches. After 4 years of use (during which time I changed the film with the alien lifetime program 3 times), I can say that the screen is flawless, without any scratches. That means a lot for a possible resale. Also, the feeling of the screen with the alien film is super ok, I don't feel a noticeable difference compared to using it without any protection.
