These belts are identical to my other belts. As thick and as strong as it seems. Time will tell how they hold up. Those old Panasonics just keep working, but they'll eat the belts if the pulley jams even slightly. It's always good to have extra items with you. I would buy them again if they hold up well. As I said, old Panasonic vacuum cleaners usually burn out prematurely. Despite this, the vacuum cleaner has worked flawlessly for many years.
