Frankly, it's a good product at a very good price. Yes, you need to be sure that there's no dust on the screen before applying (that's why there's a cloth included), and although it took me two attempts, it was worth doing. The air bubbles (what few there are) are easily removed using the card that's included in the pack and having six protectors - OK, four now because I had one practice and used one - should last me until the phone contract is up for renewal. A bit of care in applying it and it's a great protector. It even has a cut out for the front facing camera. I'd definitely buy this again! At this price, and bearing in mind there are six in the pack, one can't go wrong!
