Example Input: This band is pretty awesome! I wasn't sure about the adjustable part of it but it made my gym bag lighter, now I don't have to carry 3 bands. Adjusting is kinda hard but that's a good thing because it will avoid it from loosening up while you work out. The rubber ending with logo also prevents it from sliding all the way out. I'm not sure if it was made that way on purpose but it's a good feature. All in all, I am very happy with it. I used it on Smith machine while doing leg presses laying down and during squatting. It doesn't seem that way but it adds that extra burn you want when you get used to your workouts after a while especially on inner thighs which is a difficult area for all women.
Example Output: positive

Example Input: I purchased this item to use for my sons prom send off, the only balloons that were able to be used were the latex ones, no foil balloons could be used, also the discription shows a 2018, I was sent a 2019, which means the day of prom last minute I had to go and purchase the correct numbers which cost me an extra 40 dollars... I'm so disappointed..
Example Output: negative

Example Input: I began getting significant foot and calf cramps (in the night and especially in the early morning) after taking this as directed. I stopped and for a month had no cramps. The cramps resumed upon taking this again.
Example Output:
