Example Input: This item arrived in the mail a MESS! When I opened the package, I stuck my hand into goo. Not only was the lid not screwed on properly, but the container was actually cracked! See pictures! And it says “no returns”. It’s unusable! All of the liquid is in the envelope or dripping off the bottle
Example Output: negative

Example Input: I bought these on August 22nd and installed them right away. It’s been a little over a month and around 5,000 miles and they are completely warped. Very disappointed with the overall quality of this product.
Example Output: negative

Example Input: Original review:Love this and wear it all the time. It does get little balls under the arm. REAL WOOL AND SUPER WARM! Update: NOT SURE IT"S REAL WOOL!!! It didn't shrink in the washer or dryer. Accidentally washed!
Example Output:
positive
