First off, it works. I have no complaints with the actual protector.
My main (and only) issue is that it didn't come with installation instructions (unless they were on the back of the package; I don't remember looking at that). Since I have installed a few of these things on various devices, though, I knew what to do. (I did accidentally skip a step (use the dust sticker all over the tablet), but fortunately it didn't matter.)
I think it's definitely worth the money because it should protect my tablet. Since I'm not planning on trying to test it out, I'm going to have to hope it does work. 😁
