i had dust on mine when i first put it on, so i peeled it back off rinsed it under some warm water, no soap, gently shook it as dry as i could get it and put it on with a few beads of water still on it, which i took a brand new bank card and pushed the water out away from the speaker. and you cant tell it ever had dust on it, 0 bubbles and its been on for over 2 weeks now.
i have the power support anti glare.
