You're referring to iPhone screen protectors? There are threads on this in the iPhone accessories forum (you've posted in the Mac forum which is probably not the best place for this topic), for example see the link below. You'll find lots of opinions on different screen protectors, but I personally would not expect much from a $1 product. The Belkin that I use on my 13 Pro Max was expensive but it is guaranteed by Belkin and they will replace it if there are any problems (cracking, etc). I've done that with their screen protectors in the past so I can confirm that they do honor their guarantee.
It happens so frequently, when I touch the screen it wouldn't respond as expected and I have to touch again, it's really annoying. Is it because of the screen protector? But it's by Belkin, which I suppose it to be the one of the best protector in the market. Or is it because it wasn't applied...

I purchased from the Apple Store (link below just as an example, they have other screen protectors available in addition to this one). This is not necessarily the best screen protector, just the one I happened to purchase. Lots of reviews on youtube as well, where different testers give their own ratings of the various choices.
