Instruct: Classify Amazon reviews into positive or negative sentiment
Query: good

this only works well IF you put it on well. i read all the reviews and i was deciding to buy it or not buy it...let's get straight to the facts.you will not get all the dust out. you will have some on your screen. just staring at you. YES, this sucks. but if you do it right, they will hardly be noticeable. same with the air bubbles. the reviews said they go away on their own, so i'm still waiting for that.as much as the reviews said you dont have a second try, to me, i did. i actually put it on 3 times on the touch screen. here's a tip:get some really sticky tape with you, so you can get the dust out as you put it on. this is the most help i can give you.edit:im proud to say that all air bubbles are gone...after reapplying both again.this thing WORKS, as long as you do it right.
