Honestly I'm very disappointed with this belt, the metal bar used to attach the belt and buckle broke on the second use. Looking at it, it's not surprising that the stem is less than 1/8 inch wide and the threads on it go into the small stem, making it flimsy and not worth the dollar. This single failure in the belt renders it unusable even under light load conditions. Now, I might get a broken belt or clasp, so I can't say you'll have the same problem, but I'm pretty sure that even in random situations, you'll break this belt before you should. In the end, please make the thread of the main shaft wider and the female thread more rigid and better material for the shaft. God bless.
