I recently had my I pad screen replaced due to some major cracking. My IPad was in a portfolio case with a zagg screen protector on it. I am looking into getting a nuud lifeproof case, however I'm not sure if I should also invest in the zagg screen protector again or if the case by itself will be good enough. I want to ensure my screen doesn't scratch or crack again. Is there a better screen protector other than zagg? What are some of your thoughts. Thank you for your input.
