I was once no screen protector person as I didnt like the idea. Then because of obvious reasons I bought some but cheaper ones but it turn out to be not so good experience. You do get used to it with time but you really feel the difference. Like when you take it out for replacement you see a shiney neat screen and you think why o why I cant have that always.
And then finally after quite some time I took a plunge to buy costly one and now its never going back.
I use
Martin Fields now on my 2215 and you can not tell if there is anything on the screen or not. I would highly recommend anyone to spend this money once and then feel the superior experience.
