Unlike the two previous opinions, this is my second order of this product, and I am fully satisfied. Easy to apply, good duration in time. You just happen to fit well protection. No problem for me. In terms of the bubbles that form, all the protections of this type will do if they are poorly enforced. Have a handy map to smooth and prevent the air. As for any traces of dust, again, it is relative to all such protections. This product has a very good price-quality (compare with the protections to over 10 in store, you will see that the quality is exactly the same), and I recommend it as many times as necessary! At this price, I do not deprive myself.
