Looks nicely made and fits the pulley perfectly. Time will tell if it will last.

Good belt

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.

short belt life/not durable

Reviewed in the United States on October 1, 2023

The B205 belt has good traction but only last several months to a year before seriously cracking. I normally get 3 to 5 years in this application, and don't look this bad even then. I am trying some different lengths and widths in this brand, so hopefully Bestorq will perform better in those applications.
