Example Input: I've had my replacement bands for 3 months and one side has already broken. I didn't hit my fit bit on anything and wasn't messing with the band. Pretty upset I have to buy another set of replacements so soon.
Example Output: negative

Example Input: I never wanted to be a dog parent that needed one of these, but here I am. I have a year old puppy that will not listen when it comes to eating things he's not supposed to outside. It's super easy to use and I love that there are different settings. I mostly use the vibrate but when I do need to use shock I have to use at least 80 for my dog to even notice it. My use of the collar is to have my dog drop whatever is in his mouth from a distance so a lower setting might work for your dog. There's a charge port to put the collar and remote on which is awesome. The collar is also super long but you can trim it to fit.
Example Output: positive

Example Input: I’m very pleased with the purchase of this sound bar. It was amazingly easy to hook up to our tv and has enhanced the quality of sound for watching movies. I love that it hooks up so easy to my phone for playing music. Great purchase for the money.
Example Output:
positive
