I have a $5 case that I got off of Amazon for my LG G2. I had an Otterbox for my iPod 4th gen, and this is the same quality for a fraction of the price. I've dropped it multiple times on my tile floor and a few times on asphalt (fell out of my lap when I got out of the car.
No damage to the phone, no damage to the case. I have a separate screen protector because the case doesn't have on integrated (integrated SP's are stupid, what do you do if you scratch it? You're out an entire piece of your case. I bought 8 SP's for my G2 for $3).
