Are screen protectors necessary?

Cause i wasted $20 on a screen protector for my iphone & it ended getting eff'ed up there were a bunch of bubbles & it just looked horrible! I don't want to get another, can i piece of plastic really protect your screen anyway?

Yes they work and easily replaceable, nothing worse than permanent scratches it might effect the cost if you sell it later a good cover is alwas a good idea(leather flip type) ans you won't need the screen protector then.

  • What is the best iphone screen protectors to keep phone from cracking/shattering? I'm making the switch to an iphone 5 soon, and I'm wondering what the best type of screen protector is. I'm accident prone, and drop my phone quite often. I'm not interested in an Otterbox or anything that is bulky. Which screen protector will keep my screen from cracking? Also, when it comes to buying a case, what type of material would offer the most extra protection? (gel, silicone, rubber, etc.)
  • What are the best screen protectors for the iphone 4S? I just purchased my first iphone the other day and have been afraid to bring it out with me or even use it a lot until I get a screen protector and case. I looked on Amazon and there are so many different brands and styles. I also did some research, but I still don't know which one is the best. I want a good screen protector that doesn't cost too much. Which brands do you suggest? Also, do they sell cases with screen protectors in one or are they sold separately.
