High quality belts made to factory standards. They serve just like the OEMs did 30 years ago. Yes, my vacuum has 30. You can find cheap offshore replacements at a department store, two packs last about 5 vacuums and are thinner and not as dense. The cheap ones don't let the janitor do his job. It's nice to see quality parts available for those of us willing to pay a little more for quality.
