Title: durable for the price
Review: I ordered the 3 x 21 and am very satisfied with the durability of the belt. It tends to be very aggressive longer than some and cleans quite well with the crepe cleaners available for such a purpose. Stands up to the heat of a prolonged run. I will buy more when I get through the box.
