I personally love the Tech21 Evo Gem design as I think it’s a fancy and different look for your iPhone. It’s got a 3D gem design laid throughout the back that changes as light hits it at different angles.
For a simpler design, the Tech21 Evo Check with it’s geometric grid has all the same features, including their Flexshock bumper, but in a more clean package.
I’m not a big fan of the TPU design as it does attract fingerprints and grease really easily though.
BUY THE TECH21 EVO GEM OR EVO CHECK CASE
