### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Good belt
  

*by A***M on Reviewed in the United States on March 4, 2023*

If you pay $15 for a belt when the OEM cost $50… I expect to get 1/3 the life out of it. And that's the case with these. They didn't hold up for as long as I'd expect but they were cheap and worked on my sawmill. I would by again, but will buy extras.
