I got this case:
Diztronic Matte Back Black Flexible TPU Case for LG G2 for $9.99
Amazon.com: Diztronic Matte Back Black Flexible TPU Case for LG G2 (Verizon Only - Model VS980) - Retail Packaging: Cell Phones & Accessories
I used the same exact case for my galaxy nexus for 2 years, I personally like how it thin, but still has some protection from fall, and the back is made non slippery so much less chance of dropping it.
Also having the ability to put your phone face down and not worry about the screen touching the surface is great too. The folio case from LG wasn't to my liking. Seemed more in the way than useful. My vote goes to the diztronic case.
