Niquelle laying the cloth works very well, not even need to take a sticker or clean with a little water. The handling is explained and works perfectly. 1st time I spot a movie and do no bubble shape, both during and after the installation as it is not the most expensive film I've made. No effect "rainbow".
CAUTION: The film does not cover the whole screen but it is the case for all those existing, this is due to the fact that the screen of the iPhone 6 is curved at the edges.
