As advertised, it fit and has been working on my old line trimmer. Via PRIME, bought and delivered for less than a trip to the store would have cost me. Excellent.

As the title says, replaced the belt on my attic fan. The fit was exact and you can tell no corner's were cut during manufacturing. I highly recommend any product from this company.

5.0 out of 5 stars Long Lasting High Quality A60 vbelt
Reviewed in the United States on July 11, 2024
This BESTORQ A60 v-belt lasted 10 years on our whole house fan that is in our hot attic. When it finally broke we wanted to get the exact same brand. Hopefully this one will last 10 plus years like the original. We are also happy to have a back up as a spare with the 2 pack as it was not fun when the fan broke in the middle of a heat wave. We were able to get our fan back up and running in less than 24 hours thanks to Amazon’s overnight delivery.

1.0 out of 5 stars Didn’t last 6 months
Reviewed in the United States on October 30, 2024
Bought in March for riding mower drive belt (not mower deck). Installed in April and it shredded in September. Didn’t last a full season and I usually get 2-3 years from a drive belt. Won’t buy again.
