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: Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.
Example Output: negative

Example Input: My book was damaged when it arrived- bent and crinkled. I contacted the compnay right away asking for a replacement and STILL have not received a reply or a new book. Very frustrating and disappointing.
Example Output:
negative
