Quality films are not easy to find especially as there is little comparative tests. After watching some videos of the model for iphone, I decided to take this glass protection for my MotoG. I usually ask movies and here is not always easy. I took the usual precautions (laying in the bathroom after the shower -l'humidité fact that there is very little dust in suspension -) ... The phone was new and glass arises alone magically its own weight. As there was not a single dust, there is not a bubble.
The manual is well done, the installation accessories are supplied and packaging adequately protects the glass. So just a minute glass placement, support as shown in the instructions and you're done!
For the record, it's better than a movie, it seems that the screen has no protection.
