Yup its an original incase slider, i just painted the logo with a red paint sharpie.
the case itself is pretty good, but you have to make sure its clean before sliding your cell inside or else if there is a small particle it might scratch the steel on the outside. I clean it once a week.
ive never dropped my phone so i wouldnt know how it will take it. i imagine if dropped hard enough the case might crack but the phone will be fine.
im pretty careful with my phone so i dont worry about dropping it.
