I switch my case every so often. I get all my products from boxwave. They have a wide variety to choose from, and always great deals. That's why I have so many cases. From rugged, to regular tpu cases. Id say at least 40 different cases.
I have 2. An Element that I prefer but won't fit my charging back cover for the S4 and my Spigen Neo-Hybrid in silver. The Spigen is very minimalistic and makes the S4 look much like the new Samsung Alpha.
