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: Works great! I have two other similar products and this is by far the most powerful. Especially for the price! Shipping was quick and easy without issue.
Example Output: positive

Example Input: I was very excited to get this mini-PC. I was looking forward to downsizing from my tower (and it helped that the six year old tower broke down a couple days earlier). So I waited anxiously for this mini-PC to arrive in the mail. It got here and I set it up, plugged it in, even rearranged all my living room furniture to get the set-up right. Set it up and five minutes in, it crashed. Then it did it again. It crashed no less than three times in the last two hours. Then it was SIX crashes in three hours. Time to call customer support. Oh wait, this brand doesn't have a customer support phone number. Just a forum you can post on and hope they reply. Instant regret. Save yourself the headaches and trouble.
Example Output:
negative
