I have this one coming in the mail too. Got it for $7.99. Let us know what you think of it as you use it.
I love it. It's the best case I've tried so far. The grip on the sides is really helpful for me. I'm also liking the carbon fiber look on the back. Very slim. Buttons are easy to press. Nice fit. Gonna pick up some more caseology cases can't go wrong at this price.
Cases tried so far:
Apple silicone - found it slippery at times
Speck presidio grip - too bulky but big improvement over previous version
Spigen liquid armor - slippery on the sides, didn't like the pattern it left
Spigen rough armor - awesome case but didn't like the apple logo cutout
Apple leather - more grippy than silicone, mine seems hard to access mute switch probably have to do an exchange
