Bought a Scoutmaster dealer demo three months ago. After about 20 hours of use, the belt broke. Stretching it reveals cracking along its entire length. The dealer has the unit about 8 months before I purchased it. He had VPI to send a new belt and they indicated heat might be a factor. I found a previous responder's comment about ozone interesting as I live in Grass Valley, CA, the second worst location for ozone in CA. (Has to do with pollution rising up the foothills from Sacramento then remaining in our location with the coolness of evening.)
