Example Input: Excellent quality mini screwdriver set. Works well if you are setting up a stereo system I need small screwdrivers for installing banana clips or other electronic components
Example Output: positive

Example Input: I had problem with the 2 screen protectors, any of them paste well on the screen. Very disappointing because I also bought the complete screen protection and I hope not happening the same thing...
Example Output: negative

Example Input: Purchased this showerhead as a replacement for one I purchased a couple years ago This one is identical to the one purchased before....I THOUGHT!! It looks the same but it is NOT the same. I purchased the previous one at a higher end plumbing/fixture store. This one on amazon is made for mass consumption and is not the same quality. the water flow is not as great as the low of my older showerhead even though I removed the water-saver mechanism in the new one. Its a cheaper product. Ended up using the older showerhead.
Example Output:
negative
