That case is just a bumper. That means it only has protection on the edges of the phone. Yes I see that there is a back, but it's specific goal is edge protection. And doubt get me wrong, Spigen is a great company.
Let me see if I can find something for you.
Edit: Check out this case. I know it might not be as appealing, it does have better protection for the front and back as well as the edges. http://www.amazon.com/dp/B00SIG5KFS/ref=cm_sw_r_udp_awd_hbFtvb1W4VX0B
