Example Input: We bought this to limp us through not having a stove for a while. It works great! We use it to saute veggies, boil water, scramble eggs.... anything a small bottom pan can do! Heats up super quick and very easy to clean. Even once our stove is repaired, it will be in regular use in our home.
Example Output: positive

Example Input: I wish I could do half a star. I suffer from chronic neck and back pain and wanted to invest in something to relieve the pain. After reading on the different massagers, i settled on this one. My meds had worn off at 2am and the pain work me up. I decided to try the massager to get some relief until the next round of meds kicked in. I’m SUPER DISAPPOINTED! This worked for all of 30 seconds and then the nodes stopped working and the heat turned off. Seriously! Now stuck waiting in pain until meds kick in. I will be returning this item ASAP. Thanks for nothing!
Example Output:
negative
