Hi all,
Voice of customer for these models is pretty much as I put on table below.
During installation there’s nothing unusual to the belt and all going normally, but after running and using the belt for some period of time (varies but I take average usually around 3 months) the belt starting to make noises (whistling, vibrating) if not breaks for CR and EPDM normally takes 1-2 month longer until it also makes noise and vibration and the user can sometimes feel the effect on the vibration during the scooter ride.
