what do you mean its now worse? are you talking about your screen appeal?

i think you should get another one if you:
1. are not going to change phone soon
2. really need one, the only thing that bothers me is the dust casing and the screen itself
3. if your screen is already having huge markes, some protectors' adhesives fill up the marcks onf the screen and make them look better.

i think thats about it
