Screen Protector For GPD WIN 4 / GDP Win4, Tablet PC [Premium Clear] [3-Pack] Screen Protector (PET Material)

I have a lot of devices and have used lots of different screen protectors. This one is the worst I've ever used. Bubbles are almost impossible to eliminate but after I finally did it on the 3rd attempt, I found that the protector didn't stick to the screen and would almost fall off just from gravity, let alone from any kind of contact. Useless. A waste of plastic.

For the price this is a decent screen protector. So far have no issues with it and it is easy to apply without any bubbles.

Good screen protectors but could be cheaper considering they're only 3 plastic films rather than glass. They applied easily and come with a simple cleaning kit and bubble remover card.
