I have been using the stock case and the skinomi. Last night my puppy decided to knock it off the nightstand and chew on it! Luckily it came away with very little damage. The skinomi is toast but the screen is still like new. The only marks are at the top of the phone by the earpiece. I will replace the screen protector and get a new shell. I know without those protectors it would have had scratches and teeth mark all over!
