At first this appears to be the cheap version of an OtterBox, but unfortunately the screen protector is a sheet of plastic and is not sealed against the screen. Because of this the gaps for the camera the buttons and the charge at the bottom, dust and other things get underneath the screen. This affects swiping, typing and scrolling. As you are using the screen if you go over a bump, the phone thinks you've let off and then repressed in a different location.
Also the tabs that cover the charger and headphone hole don't really stay in or come out. To be clearer you really have to wedge these back to be able to get the charger into the hole. When they are pressed into the hole They Don't Really stay put and they slowly release out creating a ledge that catches. I hope it gets better with time, if it does I will rewrite this review.
