2 stars because it is rich as a package. However, it has difficulties in application, and MANY ways for something to go wrong even if you watch the video with the instructions. I did EXACTLY what it showed, and bubbles formed in one area. They appeared after I put it under the lamp. So I had to pour more liquid. But again, it didn't fill the whole area. Also, after a few days without dropping it, I found it cracked. The screen was saved, but the glass was already for the trash. Which doesn’t come off easily because it was liquid that solidified. And then, because I didn't have enough liquid (due to the bubbles I had to cover), it was useless. A lot of money for something complex that only if everything goes perfectly, might surpass others. Maybe.
