Suddenly breaking while I was bypassing for half a year after purchasing I was very scared. Genuine I could run over 25000 km, but this is a tower at JAF without having 2000 km. Strengthening belt = It was too short-lived if it could not be tough.
I use it for 3KJ jog. It is a combination of Yokozuna Pulley & Kitako's torque cam and the long belt of this KN project, but if you drop the belt firmly on the pulley side, the secondary side can take it to the outside with a nice feeling.
