The Verizon 3 pack does not stay on the screen very well by itself. It kinda just "attracts" to the screen, it doesnt actually stick on it. This makes it too easy to remove, and the edges to not stay on perfectly. I can see the protector a bit on the edges where a small amount of peeling is there since it doesnt actually stick on the screen.
But, I do use one of those hard plastic see-through cases from the verizon store, which ensures/protects the screen protector from coming off easily. They work really well together.
I do not recommend those cheap plastic film covers that you wet and stick to your phone. You risk damaging the device with water/moisture. Those protectors are also crap. They will NOT protect your phone if you drop it on the ground. The most those cheap little things will do is protect from small scratches or very small drops.
As much as the phone costs, I highly suggest investing in a hard plastic snap-on case like the colored-see-through ones in the verizon stores. It might be a little more bulky, but you will be thanking yourself one day when you drop it and it keeps your screen from getting cracked or the phone from getting some bad body damage.
Because lets face it, its highly likely your going to make that one mistake and drop it somewhere before that 2 year contract is up, and full retail can run you 500 bucks for a new phone. Since your probably going to drop it one day, make sure it has good enough protection for such a situation.
