Product review (5 stars): Good upgrade for a lot of dryers
Big Dryer tried to cut corners for years by using a pulley which had no wheel. I guess it worked well enough but the friction increase caused belts to wear out faster. I think most dryers have gone back to the wheel pulley, but mine still had the inferior wheel-free part. When the belt went I replaced the pulley too, and now my dryer is so powerful clothes turn to ash inside inside its vortex of heat.
