Input: Consider Input: This thing didn't even last on the phone. It wouldn't even install properly. I've put this type of screen protector on about 25-30 phones and thought I would give this one a try. Big mistake. Stay away

Output: negative

Input: Consider Input: Purchased as a food supplement for its proven anti-inflammatory and possible anti-cancer properties. Sufficient medical tests and evidence exists for the anti-inflammation benefits, but the anti-cancer effects are based upon studies by M D Anderson Cancer Center and appear encouraging. This product appears well-packaged and the ingredient analysis meets the guidelines for purity and potency as well as the bioperine black pepper to induce absorption.
Output: positive
