Example Input: Wearing everyday and overnight, this band is holding up great!!! The matte finish has rubbed off a bit and is now shiny, but the band looks and feels brand new. Many compliments. Would buy again.
Example Output: positive

Example Input: My cats are indoor, but I keep the windows and doors open, so fleas do have the ability to get in the house. One of my cats was starting to show symptoms of having fleas, and I opted to try this vs a visit to the vet to tell me he has fleas. Did some research, and gave this a try. I'm still on the first application, but flea issue has subsided. Also, not as smelly or greasy as other flea medicines.
Example Output: positive

Example Input: Beautiful set of markers for a great price. Cases are convenient for organizing colors. Lids are tight at first but loosen after the first opening. I used a rubber jar opener to pull and twist and that worked well, even with my old arthritic hands. Love the brush tips. Can go from detail to broader areas with ease. Beautiful used alone or layered with prismacolor pencils.
Example Output:
positive
