Example Input: I so wish I would have read this review before purchasing TWO gallons of this oil for my health issues. It reeks like a chemical rubber smell. This smell is coming from the black rubber gasket in the lid. When I called to report the situation to the company, Sabrina told me I would have to pay to send them a sample to have tested by a lab. Unbelievable. Good customer service would indicate that they would pay for the product to be returned and give me a full refund, including shipping. The product is faulty. Period. I will never order anything from this company again and do not recommend it to anyone based on this horrible customer service and lack of responsibility and ownership.
Example Output: 1

Example Input: Both of my cats (age 11) threw up for an extended period after eating just 3 of these. Into the trash they go (not the cats, the treats). Not sure what they were reacting to but thought it would be good to let other cat parents know the risk.
Example Output: 1

Example Input: In an effort to reverse augmenting high blood pressure, a physician recommended I drink hibiscus herbal tea. Kudos to Celebration Herbals for delivering the tea one day after the order was placed. I followed instructions on the box and used spring water which was  steeped for approximately ten minutes. Although the primary reason for drinking the tea was medicinal, I also wanted a flavorable tea. Sadly the taste of the tea was unexceptional. Accordingly, the next box of hibiscus tea that I purchase will not be from Celebration Herbals.
