i use the no adhesive. works great and no worries. tho it was difficult to put on with minimal bubbles. had to do it several times before i was happy with it. i also bought the psp pelican screen protector. havent tried it but herd it was easy and good to put on. screen savers are expensive and if you have to do it more than once or twice, it can add up. i bought mine at ten bucks for about 6 of em at my armed forces exchange. its more expensive out in the local community, about 15 to 20 bucks
