The screen protector that came with it was not great. It may be that I fitted it incorrectly, but if so it is quite hard to get right. The touch screen was less responsive with the screen protector on. In fact a moderately light touch in some regions was not detected at all. So I ended up not using the screen protector.
The volume and power buttons require quite a lot of force to operate with this case on. Maybe that is not a bad thing, but it takes some getting used to.
I actually dropped the phone onto a wooden floor by accident shortly after putting on this case. It seemed to protect the phone, and the case did not fly off as was common with previous cases I have owned for other phones. But the stylus did come loose. That seems unavoidable when dropping phones with a stylus, at least until Samsung innovates a bit more. So when you drop your phone, always check that you haven't lost the stylus by accident.
Overall, I am pleased with the price and quality of this case.
