Example 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
Example Output: negative

Example Input: I like how the rake like piece on the dust pan gets off the hair and dust bunnies that stick to the broom. To be honest I didn't know what the extra metal piece was for .... to extend .... until I just started this review! But I like the idea. I like this better than any other broom and dustpan set I've ever had.
Example Output: positive

Example Input: I have been impressed with this product compared to others for 2-3 times the price! Super simple to use, lightweight, easy to inflate and deflate. I can’t wait for many trips with this on the trails!
Example Output:
positive
