I've had iLLumiShield screen protectors on all of my recent electronic purchases. There's tons of companies that make screen protectors, but iLLumiShield is the one you can count on to work well. They are very durable, and have held up much better against the stylus of my Note 2 compared to some other brands.
You get three screen protectors in the pack plus a microfiber cleaning cloth and squeegee card. They are very easy to put on without getting any bubbles, so chances are the three-pack will last you a LONG time, but even if you do screw up you get a lot for your money here.
Not only do they give you 3 screen protectors, but if they wear out they will replace them for free! I've never taken advantage of the lifetime warranty, but I did have an issue with a pack that didn't seem to fit which Talkie Tech did replace without hassle. Great service and a great product!
