Example Input: This product was purchased and installed at the end of Mar this year. Its use is normal residential once a week mowing duties - by June 28 2018 this product was in pieces. Minor wear seen up to this point in that threads became visible and had to be removed in order to prevent snagging but today it peeled apart tearing two chunks out of the belt prior to snapping. Check before and after each use.
Example Output: negative

Example Input: I had my pull start on my motor for all of 3 pulls until it wore through the plastic gromet and snapped the first cord. Then the tank on the recoil spring broke which meant I had to take the whole spring out rebend it then coil it back up. Then the cord had to snap again because of rubbing on the metal. Then after that when I took the pull started off I saw that one the posts which holds the springs and ratchet pawls had snapped off. Such a pain. Not even worth the 2 dollars they pay to make it in china. Your better off starting your motor with a drill.
Example Output: negative
