To recap, the Snugg case provides a super-thin texture for an easy grip on your Galaxy S3: just pop your phone right into the case and you're good to go! I've had success using mine when I don't need the wallet case I usually use. It's important to note that it doesn't cover the screen so you might want to get a cover to protect it if that's an issue for you. I use a thin screen protector/anti-glare film, but I'm sure it was due to the slipperiness of the S3 that caused me to drop it in the first place several months ago. I never lose my grip with the Snugg case!
You can purchase yours for $14.99 here. Snugg also makes iPhone and tablet covers too!
