I would like to chime in my thoughts as well.
I ordered it from Aliexpress and was a bit skeptical because of all the different reviews here and the other thread.
Like other people said, you have to really push the bubbles out and due to it's curved edges, you really have to make sure the alignment is 99% accurate! I had to take it off and re-apply multiple times just to make sure it is aligned properly. To know whether or not it is aligned properly is the whether the sides (near the black/white boarders) are adhering properly. If it seems that the bubbles cannot be pushed out from those sides, it's probably best to take it off and re-apply again.
But once you've aligned it properly and pushed out all the bubbles, it's an amazing product. Would recommend to other people and buy more for myself. Though, it is clicky near the home button, but you don't really notice it unless you specifically press it.
One major complaint is the plastic backing though, you have to be careful taking it off or else it might break the screen protector.
Will upload pictures soon.
