[Guide Ver1.0] How to attach ESR tempered glass to iPad

Hello, this is Coffee Men who challenges many things.
Actually, I have a little talent when it comes to attaching films or tempered glass.
I prepared from removing to attaching ESR tempered glass. If you only want to see how to attach ESR tempered glass: You can watch from 02:52.
I also tried other tempered glass products besides ESR. The clarity may be better than ESR products, but the touch feeling is too hard. Personally, I recommend ESR products more. Above all, they seem to use aggressive marketing strategies and offer a lot of discounts.
The squeegee in the video is not for sale, you have to wipe it with microfiber cloth. Be careful when you peel off the attachment guide (gently).
Tip, if you fail, never attach and detach it. It can result in worse outcome.
