I believe his is a knockoff because i don't have that huge of a gap on mine there is a very slight gap that you have to be at an extreme angle and pretty close up to see where the headphone jack opening is. Either that or he should return for a better fitting one if it is a legit Element case
I don't think it's a knock off cuz I have the same gap on mine. It's really small like only 1 mm but when the other 3 sides are perfectly aligned it's annoying to me at least. For 150 bucks I expect perfection.
