Example Input: Love the comfort of these garments! I wished the panty came higher up on the waist but otherwise love love! They hold you in but not suffocating and I certainly my love the price compared with other similar products
Example Output: positive

Example Input: Very frustrated with this product. It had high reviews which lead me to purchase this glue gun. Within the first 2 minutes of using it the gun clogged up. So I exchange it for a new one thinking maybe I had a defective gun. NOPE! The 2nd gun was even worse. Clogged up almost immediately. I followed the instructions, so I know it wasn’t anything I was doing wrong. If they could fix this issue on the glue gun I would say that this product is amazing, but as it is now it doesn’t do what it supposed to.
Example Output: negative

Example Input: Very useful, our family has 4 car keys, we always can't find it immediately. Since we use this product, we can find the keys quickly. Very convenient. The product has key rings, can't lose the keys anymore.
Example Output:
positive
